FXS Port used for FAX

FXS Port used for FAX

FXS Port used for FAX


We have a site that was set up with the below config. Inbound to the fax is working but outbound is not... you just get a busy signal. We test using an analog for now. Below are the 3 FXS ports, the 3 dial peers for the 3 fax machines, and the dial peer I think they all point to (which looks like just local to me - we'll need local and LD). No other phones are having issues dial out, just the 3 FXS ports.

RE: FXS Port used for FAX

I would do a sh call active voice brief on a test call and see what dial peer the call legs are hitting. Too little info to say at the moment beyond asking if you've verified the CSS is correct.

RE: FXS Port used for FAX

Thank you for the reply. I have to verify if they tried to dial local or LD but would the command "translation-profile outgoing TYPE" in the dial peers doesn't prevent them from dialing LD?

RE: FXS Port used for FAX

After troubleshooting and getting more info they were connecting a butt-set to the FXS port and got a busy tone right away without trying to dial. Removing "direct-inward-dial" resolved the issue. Thanks
