[Asterisk-Users] Legacy PBX integration

Sun Apr 30 23:54:59 MST 2006

What does your dial command look like?

If had DID working before, all you have to do is send the same information
on to your pbx.  For example, if the telco was sending the full number
dialed on to your pbx, then you need to add to you dial command.  If the
telco was only sending, say, the last three digits, then that is all you
send to your pbx.

Basically, you need to know what the telco was sending your old pbx, and
then make sure you are sending that to *.

For example, for mine, this is what i have in me extensions.conf file:

exten => 2816040532,1,Dial(Zap/g3/210)

This will take a call from my main number and send it to my auto attendant.
My pbx picks up the 210 as being the DID number for my automated attendant.
In your case, since you already had DID functioning, you would replace the
210 with whatever your telco would have sent.  In other words, you need to
pass on whatever the telco sends to you.  You need to pass that on to your
pbx.  If before, your fax number was, say, 281-456-7890, and you receive all
ten digits from the telco, then your dial command would like this:

exten => 2814567890,1,DIal(Zap/g3/2814567890), assuming g3 is the group
assigned to your PRI, this may be different in your case.

Does this make sense?  You can use variables to expand on this so that you
don't have to have a statement for each DID, but this should at least get
you started.
