  • SIP calls coming inbound from Zultys PBX

    Hi All

    I am having problems getting a Zultys PBX to dial into ST via SIP trunk.

    I have some SIP messages, hopefully someone can shed light on what is happening here. Neil Darling, you may be the man.

    The problem appears to be with ST not able to decode the contact field. I get an error from the swith indicating this. The SIP INVITE messages are as follows. ST never replies, but I suspect because it can not decode the contact. The contact looks fine to me.

    Regards

    Mark Dutton

      I was hoping for a sensible reply to this. Not a link to a rant from what looks like a Zultys ex-employee.

        Mark, I can help you troubleshoot hands-on, but I don't think I can help you on the board. The issue is too complex for me to wrap my mind around on the board, which is most likely why no one else replied helpfully either.

          Mark:

          Contact Colin Mcguire - I know he has this setup and working.

          Send me an email and I will send you his number.
