asterisk users - Nov 2007 - dial in group

I have a TDM400 with all FXO module in it. Only one channel (say
channel 3) is plugged to PSTN. In my understand, a dial command
Dial(zap/g1/12345677) should search an available channel, which is 3,
in group 1 to make a call. However, I found that it will still use
channel 1 to make call even it hasn't plugged to the PSTN. Below are
the conf files.

--zapata.conf--
group=1
signalling=fxs_ks
context=incoming
channel => 1-8

You really only want

   channel => 3

here if it's only channel 3 that's plugged in.
