It might be opposite hangup rather then operator hangup, its a common error message, and ususally means there is an issue with the ISDN service (i had it here, my pri circuit died whilst i was on a call, and the display said opposite hangup when it had dropped).

Try restarting the system/ISDN card, as it may be a clocking issue.
I remember when the TEPRI-a's first came out there were clocking issues, and things like mobile and std numbers where the first ones to start failing.
Restart of the PRI card would fix it for a while then it would eventually come back, it took a few versions of firmware and a hardware mod to fix it, but i dont think this is going to be your issue.

We get a similar problem when the user hasnt paid their bill.... Rather than cut them off totally, the carrier lets them receive calls and call local numbers (flat rate here) but not any timed calls (long distance, mobiles etc). Just a thought.

Thanks to all that replied. A power cycle Sorted the problem

must be a clocking issue, Nameless I hope it does not become a problem

Dave, Eircom would just cut you off very odd case the will allow inbound only

You said you recyled the power and went had that problem with tepri cards when unable to dial mobiles had same problem before and found its software on tepri cards and if you reclyle power would be ok for about a month as its a ids 100 a older system might be software

Power supply in the 100 good? When one of our 100's supply started to go, the first thing that misbehaved was the PRI card...

don't know, if it starts giving trouble, he will have to upgrade

Thanks again

Ken
