yes, you are right. To my knowledge offers with no media are rarely seen. You may have difficulty getting UAs to accept it. But in principle it is legal. Paul [EMAIL PROTECTED] wrote: > Hi all, > > Many thanks for all your replies. > > One more query is that what is the difference bet

Hello Jitendra, I think we can confirm from following section in RFC 3261 13.3.1.4 The INVITE is Accepted The 2xx response is passed to the transport with an interval that starts at T1 seconds and doubles for each retransmission until it reaches T2 seconds (T1 and T2 are defined in Secti

Hi karthic, The Timers G and Timer H are used in case the INVITE Server Transaction has received 3xx-6xx response from TU and it has to retransmit these response until it gets an ACK. In the RFC 3261 nowhere it is given that for 200 OK also the Same retransmission process is applicable. Only what
