From my pbx I can’t dial a specific remote pbx IVR (I don’t know which pbx is and what type of telephone lines) , digits are simply ignored.
If I switch my outgoing sip trunk to “inband DTMF” it works (but then calls to other customers IVR fails).
Can I switch temporarily “on the fly” from my phones DTMF to be sent via inband method ?
Any thought about issue ?
