[Asterisk-Users] isdn channels busy

[Asterisk]

We've got a EuroISDN (32 channels) with a TE405p, running cvs head as of 
5 days ago.

In the past couple of days, we've hit a scenario where incoming calls to 
the * pbx from the PSTN are being marked as busy, but outgoing calls 
work just fine. When we reboot *, the problem goes away. Has anyone else 
had this ? I've attached a PRI debug below. I've changed the phone 
numbers (x & y) to protect the innocent :)

Please tell me that there is someone who has had this issue, and knows 
how to get round it. It's making my users, well, irate ...

Many thanks.

Julian
