Discussion: VOIPo State of Union

[stevech]

My experience with ViaTalk ended when they could not/did not want to make DTMFs work for IVRs. In people-speak: when I call my employer's voice mail, or my pharmacy, to key in digits, it rarely worked properly. Tech Support played a guessing game short of admitting that the problem is intrinsic. Perhaps it is due to the way they have Asterisk config. the PAP2 ATAs. They played the inband/out-of-band game, then blamed my employer's PBX/Voice mail, those being the industry standard iron used by Fortune 500.
