SIP – Session Initiation Protocol – is used for establishing and maintaining real-time sessions used in voice, video and messaging applications.
Protocol initiation goes through several steps, or message types.
For each message type, there is a Response code similar to HTTP, with 1xx being informational, 2xx/3xx being success, and 4xx, 5xx, 6xx indicating a failure.
VSM summarizes this data for Avaya Session Managers and Avaya Session Border Controllers.
See SIP Response codes over a 24 hour summary in the new SIP Response Summary Dashlet (available under Network).

Those response codes are broken down into 4 bands:
- Informational (blue): 1xx response codes
- Success (green): 2xx/3xx response codes
- Client-side failure (amber): 4xx response codes
- Server-side or global failure (red): 5xx response codes
By default all message types are shown, but it is possible to toggle based on specific message types, for example, to assess whether there are any unusual security breaches occurring, toggle off all but Registration and review the amber for authorization errors.
In the 24 hour summary panel, there is a tool tip mouse-over on the distribution bar which shows the breakdown of errors by error type.
This dashlet is a sneak preview. More coming soon!
Not seeing any SIP response code data?
- Check SIP Tracer is enabled within the configuration of your Session Border Controller, or Session Manager
- Point it to the VSM Collector IP Address, UDP port 514. The VSM Collector IP address will be assigned the IPV4/FQDN of the machine VSM is installed on. Further help configuring SIP Tracer is available here. Note for v8.0 of SBCs there is a known issue enabling the SIP Tracer, where clicking the checkbox does not save.
