Thanks Martyn for your response.<div><br></div><div>Yes some calls go out ( nearly 4 simultaneously ) and for the rest, it shows congestion. I have checked the signalling protocol its fine. Out of the 30 channels 4 get restarted normally (probably this is the reason why only four calls can go out) and rest are not, they remain in the suspended state.</div>

If the switch does not respond to RESTART (and the timer T316 expires<br>
- IIRC this is a long timeout), then no channels will be available for<br>
calls.<br>
<br>
The first thing to check I think is that your PRI board is definitely<br>
set to the right variant of signalling protocol, so that it matches<br>
that at the switch/provider. There are many variations of protocol<br>
(NI-1, EuroISDN etc), and if there's a mismatch it could be that one<br>
end or the other is using RESTART to try to recover the link after<br>
some kind of failure.<br>
<br>
Tell me, do any calls go out at all? Or is it that some calls go out,<br>
then you get congestion?<br>
<br>

Martyn<br>
