Hi all, I am trying to indentify a problem: I have 2 machines, one with Asterisk 1.0.11, the second with Asterisk 1.2.17. Both running with the same zaptel (1.2.16). Asterisk 1.0.11 running on Sarge with AMP's dialplan and the 1.2.17 running on Etch with FreePBX's dial plan. Now on both machines, I have some FXS connected (yes, I am talking about Astrinbanks...). The problem is that when I call one FXS to another on the 1.0.11 machine I can press one of the DTMF buttons and have a solid sound. On the 1.2.17 machine, the sound is cut off and only the first 0.1 seconds at the beginnin and end are passed to the other side. I can also confirm that with another dial plan the machine with cut off DTMF sound does pass the full DTMF sound (we usually leave the keys pressed for several seconds to test the sound quality). Now the fun stuff: The zapata.conf files are identical on the AMP and FreePBX setup. The other configuration I tested, is too different to help me. The default values on both machines in the end of this mail. I am probably missing something very stupid, and I would like to hear what do you think it is.
