[asterisk-users] Strange network issue

[Mike Diehl]

Well, it gets stranger...

As you can see from the syslog extract below, the phone registers every 5 
minutes quite reliably, until 19:02.  From this time forward, the phone is unable to register. 

No one touched the phone and I didn't change my RT Asterisk configuration.

Any ideas?

Mike.
