<div>Is it always the same number called? Or a different (random) number? We had a somewhat similar situation but the calls were random (at least they seemed random) across 8 PRIs. One individual PRI had an issue on the telco side. The Route Group was set to circular, so one out of every 8 outbound calls would have an issue because it hit the bad PRI. The system was large enough that no one recognized it was every 8th call. We "lucked" into finding it by setting the RG to top down. Once we did that, the call volume wasn't large enough to spill into that PRI so all calls worked. We then started testing them individually.</div> <div> </div> <div>Also, I personally would set the calling type to National, but I don't believe that has anything to do with your issue.</div> <div> </div> <div>-Go0se</div> <div> </div> <div><BR><B><I>Lemon <lemon@lemon.za.net></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT:
