After I call the external number successfully, I’m able to receive DTMF from the softphone but the PSTN’s DTMF doesn’t work.
We definitely don't want to assume anything, so I have to ask the obvious questions: who is the provider? are the DTMFs in-band or RFC2833? Any chance you can turn on full debugging and see if there are any clues? Thanks! -MC
