Hi,<br><br>Thanks foe so fast reply<br><br>I have "old" Asterisk 1.0.7 which is running on Intel Pentium 4 3GHz. The average load is less then 30% but this voice problem is happening even with one active call.<br>
The other machine with Asterisk 1.2.4 and zaptel 1.2.3 (the same CPU and load) sometimes behave in the same way. I already exclude CPU and load to be reason of this behavior.<br><br>Cheers <br> <br>Andrew<br><br>
