[asterisk-users] Silent Calls (Ghost Calls) When Picking Up Queue Calls
We're having a problem with calls coming in from our TE110P (an E&M wink
T1) through to our queues and then when someone picks up the calls goes
dead or silent. They are becoming known as "ghost calls" in our
organization. It's seems to only have cropped up in the last couple
weeks though we had the problem many months ago when the T1 clock timing
wasn't set to synchronize with the T1 (that is not the case now). Any
body else have this problem or have suggestions on where to start
looking to fix? Here's our zapata.conf, zaptel.conf and the excerpt from
the call log when the call appears to get hung up on from the T1 circuit.
Note: in the log below I saw a line that says "Released clone lock on
'Local/102@from-internal-5928,1<ZOMBIE>'". Could that be part
of the
problem?
Thanks in advance - Sascha
