I have an Asterisk 1.4.18, with zaptel 1.4.8 installed. I’m using a TE212P (2 PRI card), two PRI are in a trunk group together. This setup was working perfectly with asterisk 1.2 since we’ve upgraded to 1.4.18 we’re aving issues with DTMF detection on inbound calls. By example if I call and I press 1123 I may get something like 123 on the terminal. I realize that this issue is happening only with certain phone on certain lines. But when it happens on this particular phone, it’s happening all the time. The only way to have a better responce from Asterisk it’s to press the numbers slowly, and I will get a better response. Is there a way to tweek Asterisk for this, I know the relaxdtmf option and it did not change anything.
