asterisk users - Jan 2007 - Installed TDM02B - Problem when other end hangs up

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,

Hello,

Do you include in your zapata.conf

answeronpolarityswitch=yes
hanguponpolarityswitch=yes

There are any problems with hang up

I tried adding these parameters as you suggested, but then was unable to 
dial out at all.  Removing them allows me to dial out again, but still 
experiencing the same problem as before.

Thank you,

After playing around a bit, it appears that this is just random as far 
as I can see.  It may allow me to dial a few times, but then hangup. 
After rebooting my server, it may let me dial once and then start 
hanging up.

I really hope it's not a fight with every TDM that I will have to 
install.  After reading so many problems posted on the list, I thought I 
had got off easy, lol.

I've been working on getting this card to work correctly just about all 
day and while I'm certainly no expert, I just not sure it's a problem 
with asterisk holding the line open as others have suggested.

My reasoning follows and please let me know if I'm off base here.

1. Attempt to dial out on zap line.  CLI says it's dialing but nothing 
happens and after a while the phone company comes back with "if you'd 
like to make a call, please hangup and try again" followed by congestion.

2. Repeat attempting to dial out as many times as I like and get the 
same result maybe every time and then out of the blue, bang! it goes 
through usually just once.  Very random and rarely can I make two calls 
in a row.  If one does in fact go through, the zap line is screwed up 
for a while after that regardless if I hang up or the other part hangs up.

3. During the periods when I cannot dial out of the zap line, I can 
actually dial into that same line from my cell phone any time I like. 
Call after call, it goes through when dialing into the system.  Then I 
will attempt to dial out and same problem occurs: the zap line appears 
to dial out but nothing actually happens.

My point is that if Asterisk really did have the line stuck open, I 
wouldn't be able to dial in on that same line, right?  But I can, time 
after time, but dialing out is almost always a no go.

Am I off base?
