Hi<br><br>The update is that chan_ss7 worked flawlessly on my link with mostly
default settings.<br><br>So that means the link is not making error. Perhaps
there is a bug in libss7 or some config problem. I will update. <br><br>Thanks for looking at this. <br><br>Here is my working chan_ss7 1.4.3, wanpipe 3.5.18 and asterisk 1.6.2 config files that work with Sangoma A108 card. <br>
