try to play with d channel<br>
at /etc/dahdi/system.conf as well as corresponding<br>
settings at wanpipe.<br>
<br>
hardhdlc never worked for me, even if sangoma recommends it.<br>
<br>
libss7 use mtp2=16 !!!<br>
<br>
chan_ss7 not like at all any settings and all channels marked as<br>
bchan=1-31 !!! (yes chan_ss7 handle all signalling by himself with<br>
own stack)<br>
<br>
and you MUST turn off at wanpipe sinnalling channel like<br>
TDMV_DCHAN=0<br>
<br>
Wish You luck!<br>
P.S: don't forget play with CRC4 along!<br>
