You might want to try bri_net_ptmp since bri_net is
for point-to-point<br>
operation<br>
and you are not getting any response from the BT.
The BT may be<br>
expecting<br>
to operate in point-to-multi-point mode.
Otherwise, you may have a<br>
cabling<br>
<br>
problem.<br>

Actually I've also tried to set it in PTMP mode without
success. The BT landline<br>
seems configured in PTP BTW. Regarding the cable, it seems
to work because I've<br>
used it to connect the Panasonic PBX which indeed work.<br>

<div>The main distinguishing thing between PTP mode and PTMP
mode<br>
with chan_dahdi/libpri is the TEI being used. PTP mode
only uses<br>
TEI=0. PTMP mode uses auto-assigned TEIs.<br>
<br>
</div>
<div>You could also have an issue with terminating
resistors. Only one side<br>
</div>
<div>should have them in the circuit. If both sides have
them or neither side<br>
</div>
<div>has them then you will have communication problems.<br>
</div>
</div>
</div>

Indeed, this might be something to recheck. This might also explain
the rough minute<br>
the BT Versatility needs to synchronize against the BRI. <br>
<br>
Actually the openvox card is set to terminate the BRI line with the
usual 100ohm.<br>
