Hi All, Can you help me with the clarification? when acting as UAS and we send 200 Ok and dont receive ACK how many times should we reransmit 200 OK?
in TCP there are no re transmission so after how much time we send BYE? want to know how is T2 coming to the picture and how are retranmission handled? UDP: 0,2,4,8,16 (if T2 is 16) stop here ? (or) 64T1? TCP: when do we send BYE after T2 (or) 64T1 for not receiving the ACK RFC 3261 from section 13.3.1.4 The INVITE is Accepted Once the response has been constructed, it is passed to the INVITE server transaction. Note, however, that the INVITE server transaction will be destroyed as soon as it receives this final response and passes it to the transport. Therefore, it is necessary to periodically pass the response directly to the transport until the ACK arrives. The 2xx response is passed to the transport with an interval that starts at T1 seconds and doubles for each retransmissionuntil it reaches T2 seconds (T1 and T2 are defined in Section 17).. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
