    Hi,
    I have a SIP trunk provider who requires that we support session timers as per RFC4028.
    I have an IVR that does not support RFC2048.
    I need to connect my IVR to the SIP provider for inbound and outbound calls.

    During a call the SIP provider periodically sends a reINVITE message to determine if my IVR UA is up (to catch potential zombie calls as per RFC)
    My IVR responds with a 488 error message but my SIP provider expects a 2xx success message and so assumes that the IVR is down and so tears down the call (problem for me).

    Can I put 3CX inbetween the SIP provider and my IVR to act as a proxy, taking care of the reINVITE sent by the SIP provider whilst still letting me hande inbound and outbound calls on my IVR?

    Regards
    Paul
