It would be even better to have somehting without b2b.

From has the user that initiated the request. For a reINVITE, if the reINVITE is issued by bob, then From has bob URIs. Take a look at the examples provided in the Session Initiation Protocol (SIP) Basic Call Flow Examples RFC: https://datatracker.ietf.org/doc/html/rfc3665 As for the b2b question, take a look at b2b_sed_reply function: https://opensips.org/docs/modules/3.3.x/b2b_logic.html#func_b2b_send_reply If you need to reply with 200ok to a reINVITE, you need to make sure that the SDP in the reINVITE is the same as the initial SDP and send back the other party's SDP in 200ok. -ovidiu On Fri, Dec 2, 2022 at 11:45 AM johan <jo...@democon.be> wrote:I realise that I made an error in my drawing. 1. dialog uniqueness Alice calls Bob ->INVITE call-id: 1 from: alice@atlanta;tag=1 to: bob@boston <- 200 call-id: 1 from: alice@atlanta;tag=1 to: bob@boston;tag=2 -> ACK call-id: 1 from: alice@atlanta;tag=1 to: bob@boston;tag=2 Bob does a session refresh <- INVITE question in on the from tag and the to tag. should it be <- INVITE callid: 1 from: alice@atlanta;tag=1 to: bob@boston;tag=2 or <- INVITE call-id: 1 to: alice@atlanta;tag=1 from: bob@boston;tag=2 or are both the same dialog (call-id + the 2 tags) ?

Is there a way that I can let respond opensips 200 OK on the reinvite without forwarding the request to A ? so I want A opensips B -> invite ->invite <-200 <- 200 -> ack ->ack ... .... <-reinvite for keeeping session alive. ->200 instead of A opensips B -> invite ->invite <-200 <- 200 -> ack ->ack ... .... <-reinvite for keeeping session alive. <- reinvite -> 200 ->200 wkr, _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
