[Asterisk-Users] Ring requested on channel 1 already in use...

[Alastair Maw]

I'm running an E400P. Every now and then Asterisk stops receiving 
incoming calls.



This turns up in the messages log:

Nov 25 10:49:12 WARNING[65541]: File chan_zap.c, Line 5793

A little while back I also had this in my logs:

FWIW, my libpri/zaptel/asterisk installs are all about two months old. 
Might whatever causes this have been fixed by now? (I don't want to 
upgrade otherwise as this problem is quite intermittent).

Anyone have any ideas?
