SIP Session Keepalive mechanism/Expiration timers
Hello all,
I would like to setup ACME 3820 to handle status of sessions, do a keepalive mechanism on signaling level, it means send/process Re-INVITEs and responses, set/refresh timers or terminate call if no response (send BYE in both legs of course).
The idea is to have 2 different realm/sip-interface, access (customers) and core (softswitch).
Configuration between access and SBC should fully manage SIP keepalive mechanism, it means:
- if incoming call (access --> SBC) and refresher is set to uac SBC will respond to this Re-INVITE and maintain timers, not necessary to re-send this re-invite to the core side
