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 it says is -
"If, while in the "Proceeding" state, the TU passes a 2xx response to the server transaction, the server transaction MUST pass this response to the transport layer for transmission. It is not retransmitted by the server transaction; retransmissions of 2xx responses are handled by the TU." So can you please let me know from where I can confirm that the same Processing is true for 200 OK also.

But in case, the UAC does Not sends an ACK for the 200 OK, then how many times the 200 OK is retransmitted and At what interval this re-transmission happens (Assuming non-reliable transport such as UDP). >From RFC-3261 I am only able to find out the following Section : 17.2.1 or RFC - 3261 says "If, while in the "Proceeding" state, the TU passes a 2xx response to the server transaction, the server transaction MUST pass this response to the transport layer for transmission. It is not retransmitted by the server transaction; retransmissions of 2xx responses are handled by the TU." So please tell me how many times the TU will retransmits 2xx for which it has not an ACK.
