Sangoma's Support appears to be clueless as well, they didn't have<br>
effective suggestions so far(Opened a ticket 2 weeks). Since i don't<br>
have this problem with identical hardware without<br>
Sangoma-Cards(SIP-Trunk instead), my first assumption was the card.<br>
Probably an interrupt issue?<br></blockquote><div><br></div><div>Another test you can try to pinpoint the issue and determine once for all if the problem is below FreeSWITCH is to use the "ftdm trace" command. This command</div>
