asterisk users - May 2008 - Asterisk Wackyness

Here's a weird one. We have a situation where Asterisk seems to be losing
it's ODBC database connection during idle periods. A workaround was to have
a script connect to AMI and generate a bogus call, which would then generate a
CDR and keep the connection alive. We didn't want to be generating actual
network traffic for this, so I tried originating a call to 1 at xxx.

Somehow, magically, Asterisk maps a bogus host name (we have no peer in our
config called 'xxx') to a IP of 205.234.182.xxx (not really .xxx...just
hiding the IP) and a a host name of unknown.ord.scnet.net. How does that happen?
I know it's doing this because I can see the SIP INVITE to out to this
address. Seems like other bogus host names also map to the same place. Time to
go and grep the source for 'scnet.net' I guess.

Doug.

Why not try 1 at localhost and see if that solves the problem for you?  I'm
going to make a wild guess here that Asterisk is trying to do a DNS
lookup on whatever you have there for "xxx".  Is your "xxx"
numeric?
I'll bet if you change it to 1 at localhost you won't see the problem.
