Guys. I have a te100p with unicall and an E1 and Im having problem with DTMF tones but the weird thing is, I only have problems sending the tones to certain phone numbers, anybody seen this behavior? Asterisk shows on the console the dtmf tone been pressed but seems the other side is not getting them, and this just happens with certain phone numbers, not all.. Any clues(tips?

This was somewhat speculation on my part, but adjusting the transmit gain down did seem to resolve it, so that was the proof. It's pretty difficult with such a huge variety of different phone systems and equipment out there to get them all working acceptably. Of course my biggest issues have been with the stupid phone system at my wife's workplace! I had to retune my gains for that system after I thought I was done... It's clearly a compromise, and I suppose if the hardware (FXO in my case) had a GOOD auto gain adjust that might help... Marty
