Tzafrir,<br><br>thanks for your answer.<br><br>I'll try to implement and test the patch you point because it seems to be the best solution for my needs.<br><br>When I was waiting for the answers here, someone has come up about another question I could figure out how to answer:
<br><br>Is it possible to do exactly the opposite? Instead of providing my own clock source, is it possible the get this clock from the zaptel layer. I'm thinking on using our software layers with another vendor cards like Digium and Sangoma. We don't use zaptel so I'm wondering to know if it is some kind of way to get this clock .
<br><br><br>Can you or someone help me?<br><br><br>Thanks<br><br><br>Paulo<br><br><div><span class="gmail_quote">On 7/10/07, <b class="gmail_sendername">Tzafrir Cohen</b> <<a href="mailto:tzafrir.cohen@xorcom.com">tzafrir.cohen@xorcom.com
