Hi All
Thanks Lonnie for your idea however this problem occurred again and stopping
Asterisk for a while did not fix it.
I had to reboot again as the only thing that fixes it ☹
There are some network issues at the site but I cant see why it causes this!
I have changed out the DSL modem so that's not it.
Any more ideas?
Regards
Michael Knill

Thanks Lonnie. Good call. That will be my next test.
PS IP Address stays the same.

Michael,
My theory has always been your problem is with an upstream firewall.
Stopping asterisk for a period of time may allow upstream firewall
states to expire.
By rebooting AstLinux you will do the same (stop/start Asterisk) and if
you have PPPoE you may pull a different IP address which will bypass any
upstream states.
From all you have described, this looks to me to be an upstream issue
relative to AstLinux.

The system needed a full reboot for the trunk to be REACHABLE
