Códigos respuesta SIP CDR VOS3000 Complete referencia de 30+ códigos

Los códigos respuesta SIP CDR VOS3000 son fundamentales para diagnosticar fallos de llamada, optimizar el enrutamiento y mantener altas tasas de completación. Los códigos de respuesta SIP son indicadores de estado de 3 dígitos definidos en RFC 3261 que cada elemento SIP genera durante la señalización. VOS3000 registra el código de respuesta SIP final en cada CDR, proporcionando una vista directa de por qué las llamadas tuvieron éxito o fracasaron. Esta referencia cubre los 30+ códigos que encontrará en los CDRs de VOS3000. ¿Necesita ayuda analizando sus CDRs? Contáctenos por WhatsApp: +8801911119966.

Los códigos de respuesta SIP siguen una estructura basada en clases donde el primer dígito indica la categoría de la respuesta. VOS3000 captura en los CDRs la respuesta SIP final que determinó el resultado de la llamada — para llamadas exitosas típicamente es 200 OK, mientras que las fallidas registran la respuesta de error que causó la terminación. Según el manual §4.5 (pág. 156-162), al analizar la distribución de códigos en los CDRs puede identificar problemas de enrutamiento, capacidad y configuración que afectan el ASR y los ingresos.

📋 Clases de Códigos Respuesta SIP

Las seis clases de códigos de respuesta SIP representan diferentes categorías de resultados de señalización. Entender la estructura de clases es el primer paso para interpretar los códigos en los CDRs.

🔹 Clase	🔹 Categoría	🔹 Significado	🔹 Impacto en CDR
1xx	Provisional	Llamada en progreso, no final	Raramente registrado como código final
2xx	Éxito	Llamada establecida exitosamente	Facturable — 200 OK el más común
3xx	Redirección	Llamada redirigida a otra URI	Puede o no resultar en llamada facturable
4xx	Error de Cliente	Fallo por problema del cliente	No facturable — problema de configuración
5xx	Error de Servidor	Servidor no pudo procesar la solicitud	No facturable — problema upstream o capacidad
6xx	Fallo Global	Llamada rechazada en todas las ubicaciones	No facturable — debe detener failover

🔴 Códigos 4xx — Error de Cliente – Códigos respuesta SIP

Los códigos 4xx indican que la solicitud contenía sintaxis incorrecta o no pudo cumplirse por parte del cliente. Son los más accionables porque a menudo señalan problemas de configuración que los operadores pueden resolver directamente.

🔹 Código	🔹 Nombre	🔹 Causa Común en VOS3000	🔹 Solución
400	Bad Request	Mensaje SIP malformado	Verificar headers SIP y dial plan
401	Unauthorized	Credenciales de autenticación incorrectas	Verificar usuario/contraseña en gateway
403	Forbidden	IP no autorizada o cuenta bloqueada	Verificar lista de IPs y estado de cuenta
404	Not Found	Número no enrutable	Agregar prefijo a tabla de rutas
407	Proxy Auth Required	Proxy requiere autenticación	Configurar credenciales de proxy
408	Request Timeout	Sin respuesta del gateway en timeout	Verificar disponibilidad y red
480	Temporarily Unavailable	Destinatario fuera de línea o DND	Verificar registro del destinatario
486	Busy Here	Línea del destinatario ocupada	Normal — habilitar busy stop switch
487	Request Terminated	Llamada cancelada por originador	Verificar colgado prematuro o timeout

🟠 Códigos 5xx — Error de Servidor – Códigos respuesta SIP

Los códigos 5xx indican que el lado del servidor falló al procesar la solicitud. A menudo están fuera de su control directo, pero entenderlos ayuda a identificar qué carriers tienen problemas. Para más información sobre failover, consulte nuestra guía de enrutamiento de llamadas.

🔹 Código	🔹 Nombre	🔹 Significado	🔹 Acción
500	Server Internal Error	Gateway encontró error inesperado	Contactar proveedor del gateway
502	Bad Gateway	Gateway upstream devolvió respuesta inválida	Verificar salud del gateway upstream
503	Service Unavailable	Gateway sobrecargado o en mantenimiento	Enrutar a gateway alternativo
504	Server Timeout	Sin respuesta del servidor upstream	Verificar ruta de red al upstream

⚫ Códigos 6xx — Fallo Global – Códigos respuesta SIP

Los códigos 6xx son fallos globales que indican que la llamada no debe reintentarse en ninguna otra ubicación. Cuando VOS3000 recibe una respuesta 6xx, debe detener la conmutación de failover y registrar el código en el CDR. Para configuración de failover, consulte nuestra guía de optimización de enrutamiento. ¿Necesita asistencia? Escríbanos por WhatsApp: +8801911119966.

🔹 Código	🔹 Nombre	🔹 Significado	🔹 Comportamiento Failover
600	Busy Everywhere	Todas las ubicaciones reportan ocupado	Detener conmutación
603	Decline	Llamada explícitamente rechazada	Detener conmutación
604	Does Not Exist Anywhere	Número no existe globalmente	Detener conmutación
606	Not Acceptable	Descripción de sesión no aceptable	Verificar negociación de codecs

📊 Códigos SIP y Correlación con ASR

Analizar los códigos respuesta SIP CDR VOS3000 junto con las métricas de ASR revela qué códigos están reduciendo las tasas de completación. Un despliegue saludable debe mostrar 200 OK dominando la distribución de CDRs.

🔹 Distribución	🔹 ASR Saludable	🔹 ASR Degradado
200 OK	Superior al 70%	Inferior al 50%
4xx total	Inferior al 15%	Superior al 30%
5xx total	Inferior al 10%	Superior al 20%
486 Busy	Inferior al 10%	Superior al 20%

❓ Preguntas Frecuentes sobre Códigos Respuesta SIP en CDRs

¿Qué código SIP indica una llamada exitosa en VOS3000?

En los CDRs de VOS3000, un código SIP 200 OK indica que la llamada fue establecida y contestada exitosamente. Este es el código de éxito estándar definido en RFC 3261 que confirma que el INVITE fue aceptado y se estableció una sesión de medios. Todas las llamadas con 200 OK como respuesta final son típicamente facturables (asumiendo duración mayor a cero), y un alto porcentaje de 200 OK relativo al total indica un ASR saludable.

¿Qué significa SIP 503 en mis CDRs?

SIP 503 Service Unavailable significa que el gateway terminador o servidor no puede manejar la llamada debido a sobrecarga, mantenimiento o restricciones de capacidad. Es uno de los códigos de error más impactantes porque reduce directamente el ASR y a menudo activa failover de gateway. Si los 503 son frecuentes desde un gateway específico, ese gateway puede estar subdimensionado. Puede usar la función Replace Failed Reason para cambiar cómo VOS3000 maneja las respuestas 503.

¿Cómo reducir errores 408 Request Timeout?

Los errores 408 indican que VOS3000 envió un INVITE pero no recibió respuesta dentro del timeout configurado. Para reducirlos, primero verifique que el gateway destino esté en línea y accesible. Luego revise la conectividad de red y la latencia. También puede ajustar los parámetros de timeout de INVITE, pero aumentarlos demasiado elevará el PDD para todas las llamadas. Verifique si el gateway está descartando paquetes silenciosamente por firewall o NAT.

¿Por qué veo 403 Forbidden en mis CDRs?

SIP 403 Forbidden aparece cuando VOS3000 rechaza la llamada porque la IP origen no está autorizada, la cuenta está deshabilitada, o una política específica impide la llamada. Verifique la configuración de autenticación del mapping gateway, confirme que la IP origen esté en la lista de permitidos, y asegúrese de que la cuenta esté activa y no suspendida.

¿Cuál es la diferencia entre 486 Busy y 600 Busy Everywhere?

SIP 486 Busy Here significa que un endpoint específico reporta ocupado, pero otras ubicaciones podrían aceptar la llamada — VOS3000 puede continuar failover a gateways alternativos. SIP 600 Busy Everywhere es un fallo global indicando que todas las ubicaciones conocidas están ocupadas, y VOS3000 debe detener los intentos. La diferencia clave es el comportamiento de failover: 486 permite conmutación continua (a menos que busy stop switch esté habilitado), mientras que 600 siempre termina el intento.

¿Puedo cambiar cómo VOS3000 maneja códigos SIP específicos?

Sí, VOS3000 proporciona la función Replace Failed Reason en la configuración del mapping gateway que permite sobrescribir cómo se manejan códigos SIP específicos. Por ejemplo, puede cambiar un 503 Service Unavailable a un 486 Busy Here para prevenir failover agresivo que desperdicia CPS. Consulte nuestra guía de reemplazo de códigos de terminación para detalles.

VOS3000 SIP Response Codes CDR Complete 30-Plus Code Reference

Understanding VOS3000 SIP response codes CDR data is fundamental for any VoIP operator who needs to diagnose call failures, optimize routing, and maintain high call completion rates. SIP response codes are 3-digit status indicators defined in RFC 3261 that every SIP element generates during call signaling. VOS3000 records the final SIP response code in each CDR, providing a direct view into why calls succeeded or failed at the protocol level. This reference covers all 30+ SIP response codes you will encounter in VOS3000 CDRs, organized by class with troubleshooting guidance for each. Need help analyzing your CDR data? Contact us on WhatsApp: +8801911119966.

SIP response codes follow a class-based structure where the first digit indicates the response category. VOS3000 CDRs capture the final SIP response that determined the call outcome — for successful calls this is typically 200 OK, while failed calls record the error response that caused termination. By analyzing the distribution of SIP response codes across your CDR data, you can identify routing problems, capacity issues, and configuration errors that affect your ASR and revenue.

SIP Response Code Classes Overview

The six SIP response code classes each represent a different category of signaling outcome. Understanding the class structure is the first step in interpreting VOS3000 SIP response codes CDR data efficiently.

Class	Category	Meaning	CDR Impact
1xx	Provisional	Call in progress, not final	Rarely recorded as final CDR code
2xx	Success	Call successfully established	Billable call — 200 OK most common
3xx	Redirection	Call redirected to another URI	May or may not result in billable call
4xx	Client Error	Request failed due to client issue	Non-billable — configuration or routing problem
5xx	Server Error	Server failed to fulfill request	Non-billable — upstream or capacity issue
6xx	Global Failure	Call rejected at all locations	Non-billable — should stop failover

4xx Client Error Codes in VOS3000 CDRs

4xx response codes indicate that the request contained bad syntax or could not be fulfilled at the client side. These are the most actionable codes because they often point to configuration problems that operators can fix directly.

Code	Name	Common Cause in VOS3000	Resolution
400	Bad Request	Malformed SIP message from VOS3000	Check SIP header settings and dial plan
401	Unauthorized	Authentication credential mismatch	Verify username/password on gateway
403	Forbidden	IP not authorized, account blocked	Check IP whitelist, account status
404	Not Found	Dialed number not routable	Add prefix to routing table
407	Proxy Auth Required	Outbound proxy requires authentication	Configure proxy auth credentials
408	Request Timeout	No response from gateway within timeout	Check gateway availability and network
480	Temporarily Unavailable	Callee offline or DND active	Check callee registration status
486	Busy Here	Callee line is busy	Normal — enable busy stop switch
487	Request Terminated	Call cancelled by originator	Check for early hangup or timeout

5xx Server Error Codes in VOS3000 CDRs

5xx codes indicate that the server side failed to process the request. These are often outside your direct control but understanding them helps identify which upstream carriers are experiencing problems. For more on failover behavior, see our VOS3000 call routing guide.

Code	Name	Meaning	Action
500	Server Internal Error	Gateway encountered unexpected error	Contact gateway vendor or check logs
502	Bad Gateway	Upstream gateway returned invalid response	Check upstream gateway health
503	Service Unavailable	Gateway overloaded or in maintenance	Route to alternate gateway
504	Server Timeout	No response from upstream server	Check network path to upstream

6xx Global Failure Codes

6xx response codes are global failures that indicate the call should not be retried at any other location. When VOS3000 receives a 6xx response, it should stop failover switching and record the code in the CDR. Understanding these codes helps prevent unnecessary gateway switching. For failover configuration, see our VOS3000 routing optimization guide. For assistance, message us on WhatsApp: +8801911119966.

Code	Name	Meaning	Failover Behavior
600	Busy Everywhere	All locations report busy	Stop switching
603	Decline	Call explicitly rejected	Stop switching
604	Does Not Exist Anywhere	Number does not exist globally	Stop switching
606	Not Acceptable	Session description not acceptable	Check codec negotiation

SIP Response Codes and ASR Correlation

Analyzing VOS3000 SIP response codes CDR data alongside ASR metrics reveals which response codes are dragging down your call completion rates. A healthy deployment should show 200 OK dominating the CDR distribution, with error codes representing a small percentage of total calls.

Response Code Distribution	Healthy ASR	Degraded ASR
200 OK	Above 70%	Below 50%
4xx errors total	Below 15%	Above 30%
5xx errors total	Below 10%	Above 20%
486 Busy	Below 10%	Above 20%

Frequently Asked Questions About VOS3000 SIP Response Codes CDR

What SIP response code indicates a successful call in VOS3000?

In VOS3000 CDRs, a SIP 200 OK response code indicates that the call was successfully established and answered. This is the standard success response defined in RFC 3261 that confirms the INVITE was accepted and a media session was established. All calls with 200 OK as the final response are typically billable (assuming they have non-zero duration), and a high percentage of 200 OK responses relative to total calls indicates healthy ASR performance.

What does SIP 503 Service Unavailable mean in my CDRs?

SIP 503 Service Unavailable in VOS3000 CDRs means the terminating gateway or server is currently unable to handle the call due to overload, maintenance, or capacity constraints. This is one of the most impactful error codes because it directly reduces ASR and often triggers gateway failover. If 503 responses are frequent from a specific gateway, that gateway may be under-provisioned or experiencing issues. You can use the Replace Failed Reason feature to change how VOS3000 handles 503 responses for failover decisions.

How do I reduce 408 Request Timeout errors?

SIP 408 Request Timeout errors indicate that VOS3000 sent an INVITE but did not receive a response within the configured timeout period. To reduce these errors, first verify that the destination gateway is online and reachable. Then check network connectivity and latency between VOS3000 and the gateway. You can also adjust the INVITE timeout settings in the softswitch parameters, but increasing timeouts too much will raise PDD for all calls. Also check whether the gateway is silently dropping packets due to firewall or NAT issues.

Why am I seeing 403 Forbidden in my H.323 gateway CDRs?

SIP 403 Forbidden appears when VOS3000 rejects the call because the source IP address is not authorized, the account is disabled, or a specific policy prevents the call. In the context of H.323-to-SIP translation, this code may appear when VOS3000 sends the call to a SIP gateway that does not recognize the originating credentials. Check the mapping gateway authentication settings, verify that the source IP is in the allowed list, and confirm that the account is active and not suspended.

What is the difference between 486 Busy and 600 Busy Everywhere?

SIP 486 Busy Here means a specific endpoint or gateway reported busy, but other locations might still accept the call — VOS3000 can continue failover to alternate gateways. SIP 600 Busy Everywhere is a global failure indicating that all known locations for the called number are busy, and VOS3000 should stop trying alternate routes. The key difference is failover behavior: 486 allows continued switching (unless busy stop switch is enabled), while 600 always terminates the call attempt.

Can I change how VOS3000 handles specific SIP response codes?

Yes, VOS3000 provides the Replace Failed Reason feature in mapping gateway settings that allows you to override how specific SIP response codes are handled. For example, you can change a 503 Service Unavailable to a 486 Busy Here to prevent aggressive failover that wastes CPS capacity. This feature is configured per mapping gateway and affects both routing behavior and the response code recorded in the CDR. See our termination reason replacement guide for details.

❓ 常见问题

“Response Timeout”和”Connection Timeout”有什么区别？

Response Timeout发生在被叫方在配置的振铃时间内未应答（电话振铃但无人接听）。Connection Timeout发生在VOS3000发送SIP INVITE但在多次重试后未收到任何SIP响应，通常表示网络连接问题、防火墙阻止或网关离线。

为什么类似失败会出现不同的错误代码？

VOS3000根据失败的确切点和使用的协议记录不同的终止原因。来自网关的SIP 404 Not Found产生”Not Found”，而路由表未匹配产生”NoAvailableRouter”。这种区分有助于确定问题是在路由配置还是远程端点的响应。

如何筛选CDR只看失败的呼叫？

在CDR查询中，可以筛选会话时间=0来查看从未接通的呼叫，或创建自定义数据库查询来按特定终止原因筛选。vos3000_cdr MySQL表包含所有终止信息用于高级分析。

什么导致”Codec Mismatch”错误？

Codec Mismatch发生在主叫和被叫没有共同的音频编解码器时。这通常发生在一方只支持G.711（alaw/ulaw），而另一方只支持G.729且未启用转码时。在VOS3000中启用转码或在两端配置兼容的编解码器。

❓ Frequently Asked Questions

What is the difference between “Response Timeout” and “Connection Timeout”?

Response Timeout occurs when the called party does not answer within the configured alerting time (phone rings but nobody picks up). Connection Timeout occurs when VOS3000 sends SIP INVITE but receives no SIP response at all after multiple retries, typically indicating network connectivity issues, firewall blocks, or the gateway being offline.

Why do I see different error codes for similar failures?

VOS3000 records different termination reasons based on the exact point of failure and the protocol used. A SIP 404 Not Found from a gateway produces “Not Found” while a routing table miss produces “NoAvailableRouter”. The distinction helps pinpoint whether the issue is with routing configuration or the remote endpoint’s response.

How can I filter CDR to see only failed calls?

In CDR Query, you can filter by Session Time = 0 to see calls that never connected, or create custom queries against the database to filter by specific termination reasons. The vos3000_cdr MySQL table contains all termination information for advanced analysis.

What causes “Codec Mismatch” errors?

Codec Mismatch occurs when the caller and callee have no common audio codec. This typically happens when one side only supports G.711 (alaw/ulaw) and the other only supports G.729 without transcoding enabled. Enable transcoding in VOS3000 or configure compatible codecs on both endpoints.

How do I interpret H.323 cause codes in CDR?

H.323 cause codes follow ITU-T Q.931 standard. Common codes include 16 (normal call clearing), 17 (user busy), 18 (no response), 21 (call rejected), and 34 (no circuit available). Use the complete cause code table in this guide to interpret specific values in your CDR.

❓ 常见问题

如何查看特定时间段的错误统计？

在CDR查询中，设置时间范围筛选条件，然后导出数据。使用Excel数据透视表，可以快速统计各类型错误的数量和占比，识别主要问题。

SIP 503和NoAvailableRouter有什么区别？

SIP 503是协议层面的响应码，通常来自下游设备。NoAvailableRouter是VOS3000内部的终止原因。当VOS3000自己无法找到路由时会直接生成NoAvailableRouter；当下游返回503时，VOS3000会将503映射到相应的终止原因。

为什么同一个错误有时显示不同？

错误代码可能因配置不同而显示不同。例如，当网关存在但全部离线时可能显示NoAvailableRouter，当网关在线但前缀不匹配时可能显示Not Found。需要结合具体配置分析。

如何预防错误代码相关的呼叫失败？

实施预防措施：1) 配置备份网关；2) 设置自动告警；3) 定期审计配置；4) 监控账户状态和余额；5) 建立容量预警机制。

📋 Step-by-Step SIP Call Flow (VOS3000 SIP Call Flow)

Step 1: SIP Client Registration

Before making calls, SIP clients (phones, softphones, or gateways) must register with VOS3000:

REGISTER Request: Client sends SIP REGISTER to VOS3000
Authentication: VOS3000 challenges with 401 Unauthorized
Credentials: Client provides username/password (mapping gateway credentials)
Validation: VOS3000 validates against account database
200 OK: Registration confirmed, client is now “Online”

If registration fails, check: correct credentials, account status (not locked/disabled), IP address matches gateway configuration, and network connectivity.

Step 2: Call Initiation (SIP INVITE)

When the caller dials a number:

INVITE Request: SIP client sends INVITE with called number to VOS3000
SDP Contains: Codec preferences, RTP port for media
VOS3000 Processing: Identifies calling account from source IP or authentication

Step 3: Prefix Matching & Routing Decision

VOS3000 applies routing logic to determine the destination:

Number Analysis: Extracts prefix from called number
Prefix Match: Matches against routing gateway prefix configurations
Gateway Selection: According to VOS3000 manual, gateways are chosen based on: priority number, ratio of current calls to channels, historical calls, and gateway ID
LCR Application: If enabled, Least Cost Routing selects lowest-cost matching route
Rate Application: Billing rate applied based on matched prefix

Step 4: Gateway Selection & Call Forwarding

Based on routing configuration, VOS3000 forwards the call:

Routing Gateway Prefix: According to VOS3000 manual, “when the number being called is not registered in the system, the call will be routed only to gateways which match the prefix specified”
Multiple Prefixes: Multiple prefixes can be specified, separated by commas
Gateway Priority: When multiple gateways match, selection follows priority, load balancing, and capacity rules

Step 5: Call Establishment

The terminating gateway processes the call:

100 Trying: Gateway acknowledges INVITE
180 Ringing: Destination phone starts ringing
200 OK: Call answered, SDP contains destination RTP information
ACK: VOS3000 confirms call establishment

Step 6: Media Stream (RTP)

After call establishment, audio flows between parties:

RTP Packets: Media flows between caller and called party
Media Proxy: VOS3000 can proxy media (configured per gateway)
Codec Negotiation: Final codec based on SDP negotiation

Step 7: Call Termination & CDR Creation

When the call ends:

BYE Request: Either party can initiate termination
200 OK: Confirmation of termination
CDR Record: Call Detail Record created with duration, cost, and status
Billing Update: Account balances updated

⚠️ Common VOS3000 Call Errors & Solutions (VOS3000 SIP Call Flow)

Based on the official VOS3000 2.1.9.07 manual, here are server-side call end reasons and their solutions:

🔴 Response Timeout

Description: The called party did not answer before the timeout limit was reached.

Causes:

Timeout limit reached (set by “Alerting” signal of Routing Gateway or SS_TIMEOUT_PHONE_HANGUP parameter)
Destination unreachable or not responding
Network latency issues

Solutions:

Adjust timeout parameter in routing gateway configuration
Check destination gateway connectivity
Verify network quality and latency
Review SS_TIMEOUT_PHONE_HANGUP in softswitch parameters

🔴 Connection Timeout

Description: No response to SIP message was received after specified number of trials.

Causes:

Destination gateway offline or unreachable
Firewall blocking SIP traffic
Incorrect gateway IP configuration

Solutions:

Verify gateway is online (check Online Routing Gateway)
Confirm firewall allows SIP port (typically 5060)
Check gateway IP address in configuration
Adjust SS_SIP_RESEND_INTERVAL and SS_SIP_SEND_RETRY parameters if needed

🔴 Account Locked

Description: The account is disabled or locked.

Causes:

Account manually disabled by administrator
Agent account locked (affects sub-accounts)
Balance insufficient with no overdraft

Solutions:

Check account status in General Account management
Verify agent account is active
Add balance or increase overdraft limit

🔴 Session Timeout

Description: Session expired due to SIP Timer protocol or max duration limit.

Causes:

SIP Timer protocol not receiving update signals
Session exceeded maximum duration (SS_SIP_NO_TIMER_REINVITE_INTERVAL)

Solutions:

Check SIP Timer compatibility between endpoints
Review session timeout parameters
Verify NAT keepalive is configured

🔴 Caller/Called Number Restricted

Description: Number length or prefix violates restrictions.

Causes:

Number length exceeds SS_CALLERALLOWLENGTH parameter
Prefix not allowed by gateway prefix control

Solutions:

Adjust number length limit in system parameters
Configure caller/callee prefix control in gateway settings
Check rewrite rules are applied correctly

🔴 Unregistered

Description: The terminal is not registered and not allowed to make calls.

Causes:

Device not registered with VOS3000
Registration expired
Incorrect registration credentials

Solutions:

Verify device registration in Online Phone section
Check registration settings on device
Confirm credentials match account configuration

🔴 Connection Limit Exceeded

Description: Maximum number of concurrent calls reached.

Causes:

Line limit reached for gateway or account
Capacity limit of server reached

Solutions:

Increase line limit in gateway configuration
Upgrade to higher capacity server
Review concurrent call patterns and optimize routing

🔴 The Called Not Online

Description: No appropriate device to accept this call (no matching routing gateway).

Causes:

No routing gateway configured for the destination prefix
All matching gateways offline
Prefix not configured in any gateway

Solutions:

Configure routing gateway with appropriate prefix
Check gateway online status
Verify prefix configuration matches destination numbers

🔴 Proceeding Timeout

Description: No response received from server within time limit.

Causes:

“Setup” and “Callproceeding” parameters in routing gateway exceeded
Gateway processing delay

Solutions:

Adjust proceeding timeout in routing gateway settings
Check gateway performance and processing capacity

🔴 Forwarding Loop

Description: Wrong configuration caused forwarding route to have loops.

Causes:

Circular forwarding configuration
Incorrect call forwarding rules

Solutions:

Review call forwarding settings in phone management
Eliminate circular forwarding paths
Check no-answer, on-busy, and timed forwarding rules

📊 Troubleshooting VOS3000 Call Issues (VOS3000 SIP Call Flow)

Step 1: Check CDR Records

Navigate to Data Query > Recent CDR or CDR to view call records. Important fields:

Call End Reason: Shows why the call terminated
Caller/Callee: Verify correct numbers
Gateway: Confirm routing gateway used
Duration: Check if call was established

Step 2: Check Gateway Status

Navigate to Operation Management > Gateway Operation > Gateway Status to verify:

Gateway is online and registered
Current concurrent calls vs line limit
Network quality indicators

Step 3: Analyze Routing Configuration

Check these settings:

Routing gateway prefix matches destination
Gateway priority and capacity settings
Caller/Callee rewrite rules applied correctly
Prefix control allows the number pattern

Step 4: Check Account Status

Verify in Account Management > General Account:

Account is active (not locked/disabled)
Balance is sufficient
Overdraft limit covers call cost

Step 5: Review System Parameters

Check relevant softswitch parameters:

SS_TIMEOUT_PHONE_HANGUP – Ring timeout
SS_SIP_RESEND_INTERVAL – SIP retry interval
SS_SIP_SEND_RETRY – Number of SIP retries
SS_CALLERALLOWLENGTH – Max number length

❓ Frequently Asked Questions (VOS3000 SIP Call Flow)

How do I check why a call failed?

Check the CDR (Call Detail Record) in Data Query section. The “Call End Reason” field shows why the call terminated. Use this to identify routing, authentication, or timeout issues.

Why are calls going to the wrong gateway?

Check routing gateway prefix configuration. VOS3000 routes based on prefix matching. Verify the gateway prefix matches your destination numbers and check gateway priority settings.

How do I fix one-way audio?

One-way audio is typically caused by NAT/firewall issues. Enable media proxy in gateway settings, ensure RTP ports are open, and configure NAT keepalive. See our RTP Media Troubleshooting guide.

What causes high PDD (Post Dial Delay)?

High PDD can be caused by network latency, slow gateway response, or DNS resolution delays. Check network quality, gateway performance, and consider using IP addresses instead of hostnames.

How can I improve ASR?

Analyze failed calls in CDR, identify common failure reasons, optimize routing paths, remove failing gateways, and ensure proper timeout configurations. Monitor gateway performance regularly.
