asterisk users - Jan 2005 - RE: how to manage Digium TDM04B outgoing calls

-----Original Message-----

My question 
concern outgoing calls. How can I configure my extensions.conf to get a 
PSTN line on my TDM04B card in the following order : first trying on the 
channel 4 then if 4 is busy then switch to 3 if 3 is busy then switch to 
2 and if 2 is busy then say there's no more line available. I don't want
to dial on the first channel as it's my main number and all calls are 
received by that channel if the line isn't busy. I don't have to manage 
it for incoming calls (it can't be done anyway) as it's done not on my 
side but on the side of my provider (with the callforward on busy thing) 
but for outgoing calls the asterisk server must manage it.

-put all of the zap channels in a group and specify that you want the
outgoing calls to choose from the back of the group.  Look on the wiki for
the g and G options to the Dial()application.
<snip>
So if you think the server can handle 5 TDM400P cards let me know. If 
not what FXOs device I should purchased? I don't want to switch to PRI 
for now (I know it would be easier to setup that way) as will be moving 
to a new building in a year or so and don't want to invest on that for 
now (as there's only one PRI provider where we are currently)

-you will probably have issues with that many zap cards in one server.  Look
at the IAXy as an ATA for the fax machines (be careful, faxing over IP can
be FUN!)or look at having a couple of machines sitting next to one another
that are trunked together.

Good Luck!

The above is good suggestion.  If you do not wish any calls to be
placed from channel 1, you can put channel 1 in a group and 2-4 in
another group.  The two groups can have the same context so that
incoming calls are treated the same way.  In your dial plan, you can
Dial() outgoing calls using the second group only.

I would suggest keeping the fax lines out of asterisk, and thereby
reducing the number of FXO/FXS cards on the server.

I would also suggest that while it is possible to do something, it is
not always wise :) See the significant volumes of reports in the
archives regarding multiple zaptel cards in one system. (PS, someone
used to keep piping up about not having this problem with yellow dog
linux on a mac, but I personally know nothing about it .....

Regards,
Adam

I must be lucky: I have 2 X100P and a TDM400 with zero IRQ or other
issues. And double NAT for the voIP part. :)

Are you using PC or mac?
