        Hi Bogdan,

        yes I do.

        I've copied the extract of the log with the processing of the
        180 Ringing, just in case you need any more
        info.

        Kind regards,
        Giuseppe

            Hi Giuseppe,

            Do you see in your logs any entries for "b2b_tm_cback"
            when the 180 is processed ?

                Hi,

                I'm trying out the b2b module on opensips and have
                encountered an issue regarding PRACK.

                In particular I have a scenario where the called
                number replies with a 183 session progress (Require:
                100rel and RSeq: 1) and then a few seconds later with
                a 180 Ringing (Require: 100rel and RSeq: 2).

                What happens is that opensips correctly replies with a
                PRACK to the 183 response but then doesn't do the same
                when it receives the 180 provisional response.

                Excerpts from the logs show this happening when the
                183 message is received:

                Aug  9 17:31:14 [2528] DBG:b2b_entities:b2b_tm_cback:
                Found require hdr
                Aug  9 17:31:14 [2528] DBG:b2b_entities:b2b_tm_cback:
                Found 100rel header
                Aug  9 17:31:14 [2528] DBG:b2b_entities:b2b_send_req:
                start type=1

                but when the 180 response arrives, there are no
                similar entries.

                It is my understanding that from a SIP signalling
                point of view the b2b module should reply with a PRACK
                to the 180 response too or am I missing something ?

                Any ideas as to why this may be happening or could it
                be a bug ?

                Many thanks,
                Giuseppe
