I think I have a site where this is happening, but all I see is a
series of outbound calls, which look perfectly normal, but at some
"random" point, ISDN channels stop being available, until they run
out. It can go anywhere from weeks down to a couple of hours before
failing, which makes it even more mystifying.
This site it unique (to us) in that it is in Ireland, and not mainland
UK - We do not believe we see the problem anywhere else, so it could
perhaps be encouraged by a local telco setting - I'll feed back if I
discover any more info.
