[Freeswitch-users] Puzzling DTMF problem

[Mario G]

The DTMF worked fine calling from anything not going through FS. But it is now resolved…. I upgraded from FS 1.6.2 to 1.6.6 and there is a big improvement in DTMF recognition. Thanks for the responses.

I realized with one providers the tones were really flat with a "pep" kind of sound as opposed to other telcos. I believe some providers degrade the quality of the call, including DTMF, past their switches making unusable downstream.

I am still baffled why a auto attendant would work at the beginning then completely stop working. I can reproduce it every time. I wonder if the other end ‘transfers” to a different AA. Either way I wish I could get DTMF to work all the time.
