Have a strange issue with an installation where other IVRs, especially those at Government agencies aren’t detecting pressed keys on our outbound calls.
We’re running FreePBX 126.96.36.199, Asterisk 11.4.0 with Cisco SPA303-G1 handsets and 4 POTS lines through a Sangoma A200 card.
Everything else is working perfectly, is this something I should try to troubleshoot with the telco?
So far I have tried adding the following to chan_dahdi.conf:
It did not make a difference.
Any help would be appreciated, am at a loss after some searching, am I using the wrong terminology?
