Hi, I don't know about Kamailio or other servers. But to test simultaneous calls, you don't require different PC. Only you require is different user ids and hard ware units (if you are testing media also). We can same port for entire sip signalling. For media, we should use different ports for

Hi all, I have a doubt regarding Cseq value while processing 3xx responses. According to RFC 3261 8.1.3.4 the new invite request for the redirected address can use the same Cseq value. According to RFC 3665 3.6 call flows, the CSeq value is incremented for the new invite request while processing t

Hi Tarun, I have no exact idea abut SBC ,like how to check the traces as i'm new to this SBC I compared the 200 OK messages for successful and unsuccesful call and there is nothing seems to be wrong. Also in Wireshark traces we have logs for Failed and successful call (same A party and B party)

Hi Tarun, According to the old saying "Be liberal with receiving and strict while delivering", B2BUA is doing best attempt to succeed the call. Are you sure the BYE has come for intended Dialog? (Does the Call-Id, From-Tag, To-Tag match?). If BYE is catching 481, it means dialog matching rules h
