    I have a couple of users on the same local net that are having declined reinvite issues at the 15 minute mark in their calls. The end phone is Yealink T46S for all users experiencing the issue.

    Firmware is not the latest, but the latest supported. 66.82.0.20 (66.82.0.30 being the latest but shows as unsupported in 3cx when updated).

    The server is cloud-hosted v15.5. Phones provision correctly, calls received and made correctly. Trunk provider (Appia) says they see the rejection error 488 Not acceptable here.

    This is the only client we are seeing with this issue. 'Supports Reinvites' is enabled for all extensions experiencing this issue.

    Thanks in advance for any assistance.

    Hello @tparker

    Are the phones provisioned using STUN or SBC? Do you other phones at that site that do not experience the same issue?

    Provisioned through STUN

    All phones at this site experience this issue.

    The trunk provider says that the IP of the PBX kicks back 488 (Not Acceptable Here) and then sends the BYE.
