    We previously had 15.5.3849.1 running on Windows

    Our provider is Anveo running a SIP trunk from the provider into our PBX

    Since the upgrade all our calls terminate after ~32 seconds. The call can just be in the PBX itself not even routed to a phone ( We have a recorded message that plays for 45 seconds giving our address so we can test the call length easily and remove the phone from the equasion )

    An inspection of the logs shows that there is no ACK that is being received by Anveo and the call is terminated.

    Has anything changed in this latest version that would cause such an issue?

    I also have problem with Anveo since upgrade -- can't register at all.
    Typically the 32 sec. problem means issues with NAT -- try running firewall checker in 3CX.
    The issue typically results in one-way audio or no-disconnect. You can check with Wireshark -- some packets been lost, as not NAT-ted properly.
