[Asterisk-Users] HELP - ! No D-channels available!

[Julian Lyndon-Smith]

We've had no problems for a few weeks running "Asterisk 
CVS-D2005.10.28.07.54".

However, this morning, we're getting users complaining that they were 
cut off - and I found these in the logs. This has happened 5 times this 
morning, and there is an entry in the log at the appropriate time.

Is this a BT issue ?
