asterisk users - Jun 2005 - TDM400P & Channel Group

I installed a TDM400P with 4 FXO modules.  Before moving all of my
office phone lines to it, I decided to move only one for testing.  I
plugged it into port 4 on the card.

In zaptel.conf I have:
fxsks=1-4

And zapata.conf:
context=incoming
signalling=fxs_ks
busydetect=yes
callprogress=no
musiconhold=default
usecallerid=yes
callerid=asreceived
group=1
channel => 1-4

When I launch an outbound call as ZAP/g1/${EXTEN}, Asterisk goes to
Zap/1 and I hear dead air because there is no line attached to that
port.  Shouldn't it be smart enough to go to Zap/4 as the only available
port in the group?

Thanks,
Adam

-you obviously read the wiki enough to know about g1 as a parameter telling
* to grab the first available line in group one *from the front to the
back*.  Look at the wiki again and look for the G1 parameter.  

In either case, I don't believe that * would skip over a channel that
didn't
have an active line attached to it because that channel is not seen as
offhook (in use).  It would still grab the 4th line in your case and you
would get dead air.

I guess that my definition of "first available trunk" (either forward
or
backward) differs from Digium. I would think that the card should know
which ports had an electical signal attached.

No, asterisk doesn't do dialtone detection. Try ZAP/G1/${EXTEN} which
means to search from the highest number port downward, or else just plug
your phone line into port 1.
