All,<br><br> I've got a problem on my SS7 implementation. When I originate calls across my SS7 link and the call lands on a PRI, I get no audio in either direction. The stack I am using is:<br><br>Asterisk 1.6.2.13<br>
DAHDI 2.4.0<br>libss7 1.0.2<br>libpri 1.4.11 (not sure if i need that, but thought it might be needed for ISUP stuff)<br>WANPIPE 3.5.15.4<br>Linux Kernel 2.6.18-194.11.4.el5 on Centos 5.5<br><br>The whole stack was hand compiled on the server (not from repos).<br>
<br>My dialplan is pretty simple, possibly too simple:<br><br>exten => _XXXXXXX,1,Dial(DAHDI/g0/${EXTEN})<br>exten => _XXXXXXX,n,Hangup()<br><br>My chan_dahdi.conf looks like this:<br><br>;autogenerated by /usr/sbin/wancfg_dahdi do not hand edit<br>
