[asterisk-users] channel.c: Unable to request channel ZAP

[Forrest Beck]

What does "zap show channels" show?  Are all the channels shown as in
use? What is set in zapata.conf for resetinterval= ? If anything.  I
believe that resetinterval is used to reset unused channels for any
channels that are left open.
