[Asterisk-Users] PRI Errors

[Andrew McRory]

I've been running Asterisk CVS-02/29/04-12:09:10 for a couple of weeks 
with no real incidents...

LEC-PRI --- T400P ----- * ----- SIP/IAX
			|
			|----- MicroCom ISPorte (faxserver)
			|
			|----- Max4004 (dialup)
		
This configuration has added some flexibility we didn't have before and I
love it but two weeks of uptime the following errors appeared in the logs.
All connections were dropped. Is this an * problem or something on the
PRI?

It happened at 3AM so it wasn't a big deal this time but I hate to see it
happen in the middle of the day.
