[asterisk-users] Installed TDM02B - Problem when other end hangs up

[Lee Jenkins]

Hi everyone,

I just installed a TDM02B and surprisingly, I had really no problems 
except one.

If I place an outbound call on the Zap line (Zap/3), everything works 
fine except when the called party hangups before I do.  I do get 
congestion, but that is expected.  However, when I try to make another 
outbound call using that Zap line, the CLI shows that the call is being 
dialed, but nothing happens and I get the telco's message "if you'd like 
to make a call, hang up..." after a few seconds.

If I call out to a party on that Zap line and hangup first, I do not 
experience that problem.  It looks like Asterisk is not getting the 
termination signal from the telco (Verizon) when the other party hangs 
up first.

Running show channels at any time after the call is disconnected (by 
either party) shows 0 active calls/channels.

When the problem occurs, calling that ZAP line from outside seems to 
reset it as well.

I'm sure it's something obvious I've overlooked, but I'd appreciate any 
pointers.

Thank you,
