    32second disconnects - logs for "500 Server Internal Error" after ACK

    Hello

    I'm trying to find logs to give me a clue to track down a 500 Server Internal Error that is terminating all calls after an ACK from the provider.
    The calls end after 32seconds.
    It's a sip trunk between our ASBCE and a cloud provider.

    I've been searching for troubleshooting guides, but most of the ones that mention a 500 error just kind of say "yeah, you don't want this one it sucks." I agree.

    Running traceSBC showed some errors in SSYNDI logs that match timestamps of the disconnect in the trace, but I can't decode them:
    [08-06-2024:16.53.03.244285] ERR#No Route Header; No Connect-To Header No Next Hop Route; But request uri is self.#[sip_routing_common.c:428] 139893460170496 (null) (null) (null)
    [08-06-2024:16.53.03.244332] ERR#Failed to route request. Sending Error Response#[SipB2bUasInviteConnected.cpp:130] 139893460170496 (null) (null) (null)

    Could this be a return route thing? I'm not a phone guy but I'm trying to digest all the materials I can find.

    Thanks in advance for any direction of what to look at - any log files or anything.
