๐ What is VOS3000 Parameter Description
Reference: VOS3000 2.1.9.07 Manual, Section 4.3.5 (Pages 222-252)
The VOS3000 parameter description framework organizes all configuration settings into a hierarchical structure that reflects the functional architecture of the softswitch system. At the highest level, parameters are divided into three primary categories: VOS3000 server parameters, softswitch parameters (including H323, SIP, and system subcategories), and audio service parameters. Each category controls specific aspects of system behavior, and understanding these categories is crucial for effective system administration. The VOS3000 softswitch platform contains over 200 configurable parameters that control every aspect of system behavior, from billing precision and alarm thresholds to SIP timer values and media proxy settings.

โ Frequently Asked Questions about VOS3000 Parameter Description
What is the most important VOS3000 parameter description for billing accuracy?
The SERVER_BILLING_FEE_PRECISION and SERVER_BILLING_FEE_UNIT parameters are critical for billing accuracy. These parameters control the decimal precision and billing unit for charge calculations. Configure these parameters according to your business requirements and regulatory requirements for billing precision.
How do I enable NAT keep-alive in VOS3000 parameter description?
To enable NAT keep-alive, set SS_SIP_NAT_KEEP_ALIVE_MESSAGE to a non-empty value (default is “HELLO”). If this parameter is empty, NAT keep-alive is disabled. Configure SS_SIP_NAT_KEEP_ALIVE_PERIOD to control the interval between keep-alive transmissions (default is 30 seconds).
What happens if I set SS_SIP_SESSION_TTL too low?
Setting SS_SIP_SESSION_TTL too low (below 90 seconds) may cause frequent session refresh messages, increasing network traffic and potentially causing call quality issues. The minimum recommended value is 90 seconds as specified in RFC 4028. Values below this may trigger “422 Session Interval Too Small” errors from endpoints.
How do I disable automatic report generation?
To disable automatic generation of specific reports, set the corresponding SERVER_REPORT_ parameter to “Off” in the System Parameter interface. For example, to disable the Agent Income Report, set SERVER_REPORT_AGENT_INCOME to “Off”. Disabled reports can still be generated manually through the client interface.
Can I use VOS3000 parameter description to limit maximum call duration?
Yes, use the SS_MAX_CALL_DURATION parameter to limit the maximum call duration for all calls. Set the value in seconds (0 means unlimited). This parameter is useful for preventing runaway calls and controlling costs. Individual accounts may have additional duration limits configured in their settings.
