SIP Methods

On a per trunk group basis, the METHODS parameter disables SBC support for particular SIP messages. For SIP calls in some environments, the following SIP messages are not recognized and supported. This facility allows you to similarly disable support for these messages in the SIP software. When support for one of these SIP message types is disabled, the message is rejected with a 405 code.

  • OPTIONS
  • REFER
  • SUBSCRIBE
  • NOTIFY 
  • INFO
  • REGISTER
  • MESSAGE
  • PUBLISH

SIP Timer and Retry Counts

SIP protocol timers and retry counts are configurable on a per-SIP trunk group basis.

SIP Statistics

The SBC collects a variety of SIP statistics including the number of requests and responses of each type and various errors. These statistics are collected on a per SIP trunk group basis and include both current and interval statistics. The default interval is 15 minutes, but is configurable. The SIP Statistics are divided based on the following objects:

  • callCurrentStatistics
  • callFailureCurrentStatistics
  • callFailureIntervalStatistics
  • callIntervalStatistics
  • gwSigPortStatistics
  • gwSigPortStatus
  • h323SigPortStatistics
  • h323SigPortStatus
  • peerPathchkStatus
  • peerQosStatus
  • peerSurrRegStatus
  • sipArsStatus
  • sipCurrentStatistics
  • sipIntervalStatistics
  • sipOcsCallCurrentStatistics
  • sipOcsCallIntervalStatistics
  • sipPeerCacStatus
  • sipRegAdaptiveNaptLearningStatistics
  • sipSigConnStatistics
  • sipSigConnStatus
  • sipSigPortStatistics
  • sipSigPortStatus
  • sipSigPortTlsStatistics
  • sipSigTlsSessionStatus
  • sonusSipSigPeerOvldStatusEntry
  • trafficControlCurrentStatistic
  • trafficControlIntervalStatistics
  • trunkGroupQoeStatus
  • trunkGroupStatus

To view statistics from CLI, enter the command:

> show status addressContext default zone <zone> <statistic>

For example:

> show status addressContext default zone core callCurrentStatistics
