SIP Session Timer
SIP session timer is implemented in the SIP ALG as per RFC 4028.
SIP session timer defines a keep alive mechanism for the SIP sessions using the periodic session refresh requests
from the user agents. The interval for the session refresh requests is determined through a negotiation
mechanism. If a session refresh request is not received within the negotiated interval, the session is assumed to be
terminated.
For more information on the SIP session timer support, See section 8.0, Proxy Behaviour in the RFC 4028.
You can use the WebUI or CLI to enable the SIP session timer and set the session-expiry timer value using the
WebUI and CLI.
Using the WebUI
1. Navigate to the Configuration > Advanced services > All Profiles page.
2. Expand Other profiles under the Profiles section and click SIP Settings.
3. Enable the session timer by selecting the Session Timer check box under the Profile Details section.
NOTE: This release of ArubaOS does not support the configurable Min-SE parameter for SIP ALG. Therefore, the ALG will not
generate the 422 responses for the session refresh requests.
NOTE: SIP Session Timer can be configured only for SIP over UDP.
