asterisk users - Jan 2010 - DAHDI and Analogue lines (UK)

Have an intersting issue whem migrating a site from Zap on 1.3 to DAHDI on 
1.4.. Nothing special about the hardware - older TDM400 card, 2 red 
modules fitted...

Both channels work fine under 1.2/Zaptel. With 1.4/DAHDI both channels 
still work OK, but only for one line - the 2nd line causes it to refuse to 
dial-out no matter which port it's plugged into.

The Lines are bog-standard BT analogue lines and we're about 2Km from the 
exchange. Both sound good to me and dial out OK with a test phone 
connected to them, but only one will dial-out via the PBX.

This is what I see:

[Jan  1 05:14:14] WARNING[1200]: app_dial.c:1237 dial_exec_full: Unable to
create channel of type 'DAHDI' (cause 0 - Unknown)
   == Everyone is busy/congested at this time (1:0/0/1)

And yet the line isn't busy or congested - nothing's using it.

The output of dsx*CLI> dahdi show status
Description                              Alarms     IRQ        bpviol     CRC4
Wildcard TDM400P REV E/F Board 5         OK         0          0          0

is fine, as is:

dsx*CLI> dahdi show channels
    Chan Extension  Context         Language   MOH Interpret
  pseudo            default                    default
       1            incoming                   default
       2            incoming                   default

So I'm a bit stuck. Why doesn't DAHDI like that particular line? What
does
it do to it that Zap didn't?

What does

What version of Zaptel?

What is the value of 'InAlarm' from 'dahdi show channel 2' ?
