asterisk users - Aug 2004 - Line death not recognized on TDM400P?

A customer of mine has 3 TDM400P cards in a box running asterisk.  On 
each card he has four FXO modules.  

I have set up the dialplan to dial via group 1 for an outgoing call.

Channels 1-12 are in group 1.

If he plugs a telephone cable into socket 2 or 3 etc, but not 1, when 
he dials out, it still tries to make the call via socket 1.

Straight away the console says that it has dialed the number via g1 
and that it is connecting sip/bla with zap/1-1 (or some such)...

On my X100P I get a red alarm if the phone cable is not plugged in.  
Is there any way to do this with the TDM400P?

They would like to be able to unplug lines and use them for other 
purposes at times.

Make sense?

I kinda thought that asterisk would realise that nothing was 
connected to the TDM card and try the second socket, the third etc...

Any help greatly appreciated.

Cheers,

Matt Riddell

The problem is, if lines 1,3,4,5,6,7,8,9,10,11 and 12 are plugged in, 

you would only be able to make 1 concurrent call...(because the next 
call would try to go out line two which would never work)...maybe if 
four people called at the same time only 1 wouldn't get through but 
then the next call wouldn't get through...

Is this so?

Out of curiosity, why are they unplugging the lines?  i.e. what are these 
"other purposes" ?

It makes sense, but the code to detect unused rj11's is not in * now.

In fact, you'll find that unplugging and replugging the rj11's will
cause * to fail after a while. (At least that was the case about a
month ago and there really haven't been any changes to the fxo
software for some time.)

There are no alarms or other indicators available that would suggest
a port has failed or is unavailable.

Well number 1 was to check what would happen if there was a line 
failure.

But the other purposes were to bring online lots of fax machines in 
time of need?!

Just tried the latest CVS version with "#define ZAP_CHECK_HOOKSTATE"
in chan_zap.c.  I am using a TDM400P with 4 FXO modules.  Only port 1
is connected to a phone line.

When * starts, I cannot make any outgoing call.  All 4 Zap channels
are unavailable.  "zap show channel 1" indicated "Actual Hook
State:
Onhook" just like "zap show channel 2 (or 3, 4)" , even though
channel
1 is the one with battery.

If I unplug the RJ11 cable and then plug it back in, or if I make an
incoming call then hang up, "zap show channel 1" will indicate
"Actual
Hook State: Offhook".  After this I can make outgoing calls as Zap/1-1
is now available.

Is there anyway to make * correctly recognize the hook state upon
startup?  Thanks in advance.
