asterisk users - Dec 2004 - dialplan selection

Hello,

I would like to parse inbound Asterisk IAX2 7-digit numbers in the form of
123-4567 and strip out the first four digits, and then dial whatever number
digits remain. If I only have three digits (000-999) and have a mix of
channels (ZAP, SIP, IAX2) could someone please point out how I can use a
single DIAL command to just dial the extension regardless of the type of
channel. .. For each valid extension, I have a separate dial command anyway,
which denotes the particular channel that extension is assigned to.

I do not want to assign groups of extensions i.e., 123-A567 or 123-B567 or
123-C567 where A=ZAP, B=SIP, C=IAX2 peers respectively.

Samudra,
If I understand you correctly, you're not just looking to strip digits, but
dial an arbitrary extension without specifying the channel type in the dial
command. correct?

You should be able to accomplish this using a variable for each extension.
For example:

[globals]
X1000=SIP/1000
X1001=ZAP/1001
X1002=IAX2/1002
X1003=SIP/1003

[outbound]
exten => _123XXXX,1,Dial(${X${EXTEN:4}},10)

If the user dials 1231002, then Dial(IAX2/1002,10) should be executed.
If you have a lot of extensions then you should be able to put the variables
into a database instead.

Oops, that line should read:
exten => _123XXXX,1,Dial(${X${EXTEN:3}},10)
