    Hi,

    We are gradually migrating to v15, but for now, just upgraded from v12.6 Cloud to v14 Cloud. Beforehand, we made sure to upgrade the SBC clients on our Raspberry Pi boxes to the latest SBC release. All seemed fine with the Cloud 12.6 to 14 upgrade and remote extensions connected instantaneously, and calls sent/received worked fine.

    However, for some reason, incoming calls get disconnected after 32 seconds now. But strangely, outgoing calls work fine and have no problems. Is there a setting on the SBC client we need to adjust? Or perhaps something on the 3cx instances? For now, we reverted back to v12.6 until we can get this resolved.

    Hello @millennium2

    Disconnection after 32 seconds means that the call is being drop because no ACK message was received by the PBX. Make sure that when you upgrade to V14 the firewall checker passes to ensure there are no firewall issues.
