[Freeswitch-users] DTMF Problems! In-band detection patchy, rfc2833 not working!

[Jon Young]

Would this also be an issue/resolution with Google Voice as well?
Using Dingaling I am routing my calls to an IVR to intercept the call
from going to Google Voice voicemail.  However, the IVR won't accept
DTMF.
