[Asterisk-Users] dtmf problem

Wed Dec 21 19:49:36 MST 2005

it looks like for some reasons the brodvoice did not like my old style
config. I changed that exacly to what they have on their web and it is ok.
I also changed the codec to g726 and I am impressed with the quality.
Anyone who uses asterisk should try that. Quality is very good.
