RFC says that the UAS must send a value greater than Min-Se value in request, if UAC support session timer. If UAC does not support session-timer, then it won't care about what the Min-Se value is. UAC can always ACK 200 OK and send BYE, if it does not like something in 200 OK. >3) If 2xx response comes with a request for session timer, but >the MinSE value is less than 90s, then what is the acceptable >behavior of the client receiving the 2xx? >4) How is negotiation of 'refresher' parameter done in this case? It is mentioned in the RFC.
