Hello! Looks like list does not get this message. If it is duplicate sorry. My setup is Asterisk 1.2.26 with Zaptel 1.2.22.1, libpri-1.2.7 on Fedora Core 4.

Caller script call every number once if call was successful. I checked. Therefore there can not be duplicates in _0, there can not be multiple 99 string for a number. Looks like there is some variable problem but I did not find where is it. Because there is thousands of successful calls the script should be correct I think. Any idea why is it happen? Is it a bug or I am just blind? bye, a
