[asterisk-users] FAX over T1 Question

[Jeremy Mann]

context from-pri {
        _8505 => {
                Wait(1);
                Answer();
                SetTransferCapability(3K1AUDIO);
                Set(GROUP(ZAP)=incoming);
                Set(CDR(accountcode)=fax);
                Set(CDR(userfield)=bedford);
                Dial(Zap/25/${EXTEN});
                Hangup();

The above AEL logic is my DID for faxing.  The card wasn't detecting the 3K1AUDIO (digium TE205P rev 02) so I set it manually.  Zap/25 is on the 2nd port of the T1 connected to a channel bank.

It also appears to make it disable EC no matter what channel of the PRI the fax comes in on.

Maybe it does nothing, but it immediately fixed faxing whereas before we were having intermittent issues.

I also have that set on in-outbound modem calls from specific channels on the channel bank, they are getting as close to 56k as I've ever seen.
