Dear All, I need your help to understand a logic behind the session expires.
My doubt is. --> Invite have "session-expire" header in Invite (from UAC to UAS) --> UAS did not included "session-expire" header in 200 OK to the correspondence of initial invite. 1) So in this case what we should assume, they accepted the sent value or not? 2) If that UAS accepted the value we forwarded (1800 seconds) to them in invite, however they did not reply whereas in invite our switch sent the "refresher = uas" so in that case do our switch will send the re-invite to them before timer expires or there is no need to send re-invite for target refresh. --> In our case we sent the invite with session expire to vendor but vendor did not include any session expire value, and before time expire our switch sent the re-invite to them despite knowing the fact that we never received session expire in 200 OK from them (means there is no expiration is for this session), but vendor replied with sip 408. --> When we tried to explain them this problem they said we never agreed on session expire in 200 OK so BYE is not legal. Please help on this. Thank you in advance.
