4. How does call routing work in VOS3000?
Call routing in VOS3000 is prefix-based. The system compares destination number prefixes with routing rules, gateway priorities, rate tables, and availability to determine the most suitable route.
5. Does VOS3000 support Least Cost Routing (LCR)?
Yes. VOS3000 includes Least Cost Routing functionality that selects routes based on the lowest rate per second, while also considering gateway priority and routing quality.
6. What is a routing gateway in VOS3000?
A routing gateway represents an outbound route toward a vendor or carrier. It includes IP address, protocol settings, line limits, billing account association, and routing priority.
7. What is a mapping gateway?
A mapping gateway represents inbound traffic sources. It maps incoming calls from a specific IP or device to an account and applies authentication, billing, and routing rules.
8. What is a gateway group?
Gateway groups are used to combine multiple routing and mapping gateways into a single logical group, allowing capacity control, routing restrictions, and simplified management.
9. Can VOS3000 limit concurrent calls?
Yes. VOS3000 allows administrators to set line limits at gateway, gateway group, and account levels to restrict the number of concurrent calls.
10. How does VOS3000 handle call failover?
If a routing gateway fails or becomes unavailable, VOS3000 automatically attempts the next available route based on priority and routing rules.
11. How does VOS3000 generate Call Detail Records (CDR)?
VOS3000 generates a CDR for each call attempt. The record includes caller number, callee number, start time, end time, duration, gateway IDs, billing mode, and termination reason.
12. Where are CDR files stored?
When enabled, CDRs are written to text files in the CDR directory under the VOS3000 installation path. Files are generated hourly using a timestamp-based naming format.
13. Does VOS3000 support real-time billing?
Yes. VOS3000 performs real-time billing by deducting call charges from account balances during the call. Calls are terminated automatically if balance limits are exceeded.
14. What billing modes are supported?
Billing can be performed by phone number, gateway ID, or phone card, depending on account configuration and call source.
15. What is an account in VOS3000?
An account represents a customer or vendor entity. It controls balance, billing rules, routing permissions, credit limits, and authentication parameters.
16. What is an agent account?
Agent accounts can have sub-accounts. Charges incurred by sub-accounts are aggregated to the agent account, allowing hierarchical billing structures.
17. How are rate tables used?
Rate tables define call pricing based on destination prefixes. They are assigned to accounts and routing gateways to calculate call charges.
18. Can VOS3000 block specific destinations?
Yes. Forbidden prefixes can be configured to block calls to specific destinations, such as premium or high-risk numbers.
19. Does VOS3000 support number translation?
VOS3000 supports number transformation rules that allow adding, removing, or replacing digits before routing or billing.
20. How does VOS3000 authenticate calls?
Authentication can be performed using SIP credentials or IP-based authentication, depending on the gateway and account configuration.
21. Does VOS3000 support SIP OPTIONS monitoring?
Yes. SIP OPTIONS messages can be sent periodically to detect gateway availability. If a gateway fails OPTIONS checks, it is temporarily excluded from routing.
22. What codecs are supported?
VOS3000 supports common VoIP codecs such as G.711 and G.729, configurable at gateway and protocol levels.
23. How does VOS3000 handle NAT?
NAT traversal features include keep-alive messages, SDP address handling, and media proxy settings to ensure stable SIP communication.
24. What is call duration precision?
The system allows configuration of billing time precision, determining how call duration is rounded for billing purposes.
25. Can VOS3000 restrict calls by time?
Yes. Work calendars and time-based rules allow administrators to restrict calls during specific hours or non-working periods.
26. What alarm features are available?
VOS3000 includes alarm monitoring for gateway status, balance thresholds, system errors, and abnormal traffic conditions.
27. How are logs managed?
System logs and history alarm tables are stored in the database and can be accessed through the data maintenance interface.
28. Can VOS3000 prevent overdraft?
Anti-overdraft mechanisms prevent accounts from exceeding allowed balances by checking credit availability before and during calls.
29. What is bilateral reconciliation?
Bilateral reconciliation compares billing amounts between customers and vendors to detect deviations automatically.
30. Does VOS3000 support LRN lookup?
Yes. For number portability, VOS3000 supports LRN queries to external servers and can route calls based on returned LRN numbers.
31. Can VOS3000 forward call status via HTTP?
HTTP call status notifications can be enabled to send call events to external systems for integration purposes.
32. What is rate limiting in VOS3000?
Rate limiting restricts the number of call attempts within a defined period to protect the system from abuse or attacks.
33. Does VOS3000 support SIP header manipulation?
Yes. SIP headers such as P-Asserted-Identity and P-Preferred-Identity can be passed through, modified, or replaced based on configuration.
34. How does VOS3000 handle call failures?
Call failure causes are recorded in CDRs and categorized by server-side, SIP device, or network-related termination reasons.
35. What is a package in VOS3000 billing?
Packages define free duration, free money amount, rent period, and minimum consumption rules applied before standard billing.
36. How are packages prioritized?
Package priority determines which package takes effect first when multiple packages are assigned to an account.
