asterisk users - Nov 2008 - TDM400 (?) zap hangup

And if that ain't confusing I don't know what would be.

I bought a TDM400 with two modules (FXO, FXS) a couple or so years ago 
and ended up never using it.  Passed it along to a friend who is having 
some problems with it.  (He isn't on this list.)

We've both tried searches using Google but haven't been able to find
anything that helps.  So this is more a question of
what-the-heck-should-we-be-searching-for. :-)

The TDM400 works taking inbound calls and gives a dial tone when the
phone is picked up but as soon as a key is pressed the line (Asterisk
says) hangs up.  Asterisk is configured based on a working system but
that one only has one module inbound (FXO?)  The outbound settings are
based on docs from voip-info.org.

Does this ring a bell for anyone?  No pun intended.

Unfortunately the system is 35 miles away and I haven't got the logs
handy so I can't provide more right now.  Just hoping for a clue on
search terms.


TIA,
Rod

Dialplan issue?

What do you have in the s context there?

35 miles away is no excuse for not having logs :-)

Specifically, the debug-level logs should be able to give you the exact
reason for the hangup (among many lines of useless information).

It sounds to me like you've got the two channels pointed at a context
that doesn't exist, or there aren't extensions in that context that
match the number being dialed.  Look in zapata.conf (or chan_dahdi.conf
if you're using DAHDI) and look for the "context=" line
immediately
above the "channel=>" line for each channel.  That tells Asterisk
where
in the dialplan to look when calls come into Asterisk from those
channels.

Next, look at extensions.conf and see if those contexts exist.  For
example, if your FXS port (the port connected to an analog phone) is
channel 1, and you're trying to dial extension 500 from the analog
phone, make sure the context contains an extension 500.  

You can also check from the Asterisk CLI by typing "dialplan show
500 at context", where 500 is the extension you're trying to dial and
context is the name of the context where calls are being sent.

Thanks to Tzafrir Cohen and Jared Smith we've solved the problem.

It was a "A Series of Unfortunate Events".  The main one was, there
was
no (and then an incorrect) context= for the ZAP channel.  The incorrect 
one came about because of a miss-communication while testing.  We were 
able to dial-out but the logic in the dialplan to select a context for 
local calls, toll-free, etc. was missing.  Once we got the channel set 
to the correct context all was well.


Again thanks,
Rod
