[Asterisk-Users] dtmf tones problem with unicall and E1

[Anton Krall]

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?
