Connecting an SBC to E-Metro Tel PBX

[nathanaeldick]

Hi all,
So I set up my SIP trunk on the e metro tel and I have an Audio Codes Session Border Controller set up as well. When I try to forward calls to the session border controller the emetro tel system logs give the following error:
[2020-06-23 15:46:41.322] VERBOSE[31934][C-00000a88] app_dial.c: Called SIP/MS_SBC/5676
[2020-06-23 15:46:41.340] VERBOSE[2793][C-00000a88] chan_sip.c: Got SIP response 503 "Service Unavailable" back from 192.168.1.78:5060
[2020-06-23 15:46:41.340] VERBOSE[31934][C-00000a88] app_dial.c: SIP/MS_SBC-0000058f is circuit-busy


Wondering if anyone had some suggestions or similar issues?

Thanks,
Nathanael

The SBC rejects the request with the reason "503 Service Unavailable". You'd have to look at the SBC to figure out why.
