Thank you for the suggestion.

I tried both the Sonus and Cisco settings in the external profile (running
sofia profile external restart reloadxml after making the changes).

This didn't help, unfortunately.

If I were to make an informed guess, I would expect Cisco equipment to be at
the other end, since my ISP has a strong relationship with Cisco. Whatever
their solution for carriers is, this is likely to be it, but I could be wrong,
of course.

I find it interesting that dtmf over PortAudio works, but from the Snom phone
it does not.
