Hello *, Thanks for the information. I have some more queries, 1)When INVITE send from UAC with the session-expires value less than the Min-SE configured in the proxy, the proxy will reject the INVITE with 422 response and include the Min-SE header.After that UAC will send a new INVITE with session-expires and Min-SE returned in the 422 response. Now when RE-INVITE send with session-expires less than Min-SE then what will be the behaivour of the proxy?Again 422 will be send by proxy?
2)what is the real use behind the 422 response? when INVITE is received with session-expires less than the min-se configured in proxy then the proxy can modify the session-expires to the min-se configured value and forward the INVITE to terminating side and in the 200 OK response the UAC will be indicated with the new session-expires and if parameter refresher=uac, then uac can refresh the session considering the new session-expires.Whether this is possible? If this is applicable a INVITE may not rejected. Pls give your points.
