Outbound calls are disrupted and transfered to fax extension

I am baffled. I am running Asterisk and FreePBX with a Sangoma A101-D card. I am having issues outbound calls when answered by the other party behaving as followed:

DAHDI/i1/208241XXXX-ffc answered SIP/807-00004676
– Redirecting DAHDI/i1/208241XXXX-ffc to fax extension

I don’t have incoming fax detection turned on because we don’t use our Asterisk box at this location for incoming faxes.

The other party then hears the no service tones:

– Executing [[email protected]:1] Set(“DAHDI/i1/208241xxxx-ffc”, “__FROM_DID=fax”) in new stack
– Executing [[email protected]:2] NoOp(“DAHDI/i1/208241xxxx-ffc”, “Received an unknown call with DID set to fax”) in new stack
– Executing [[email protected]:3] Goto(“DAHDI/i1/208241xxxx-ffc”, “s,a2”) in new stack
– Goto (from-pstn,s,2)
– Executing [[email protected]:2] Answer(“DAHDI/i1/208241xxxx-ffc”, “”) in new stack
– Executing [[email protected]:3] Wait(“DAHDI/i1/208241xxxx-ffc”, “2”) in new stack
– Executing [[email protected]:4] Playback(“DAHDI/i1/208241xxxx-ffc”, “ss-noservice”) in new stack
– <DAHDI/i1/2082414125-ffc> Playing ‘ss-noservice.gsm’ (language ‘en’)
– Executing [[email protected]:5] SayAlpha(“DAHDI/i1/208241xxxx-ffc”, “fax”) in new stack

Reinvite is set to no. T.38 pass through is set to no. NAT is set to yes. I can’t figure out why this is happening or what settings to change. Your help is much appreciated!
