[Asterisk-Users] FW: channel offhook state

[Matt Love]

Hi,
Yes, I had the same. Incoming calls were fine it was just when I made
outgoing calls the line would sometimes hang and I would get "all circuits
are busy". 
Putting a butt (test) phone on the line in parallel indicated the line had
dropped back to an on hook state, although asterisk wouldn't use it for some
time. > 20 mins.
In the log it showed an error indicating it could not create a ZAP channel
when I tried to create an outbound line.

In the end I had to remove the card from the PC, run * without the card and
run genzaptelconf to remove the zap-auto entries. I also removed all the
outbound routing and removed by 4 ZAP trunks from the configs.
I then shutdown the machine and re-installed the card and let * find the
hardware and then re-ran genzaptelconf again.
Im sure there is another more appropriate solution, but im an * newbie and I
was clutching at straws!!!

Regards
Matt
