How to cut an Outbound Call

[gamba47]

Hi guys!

I need to know how can i cut a dialed number when the patterns matchs.

From the book “Asterisk the Definitive Guide 3rd Edition”:

More Advanced Digit Manipulation
The ${EXTEN} variable properly has the syntax ${EXTEN:x:y}, where x is the starting po-
sition and y is the number of digits to return. Given the following dial string:
94169671111
we can extract the following digit strings using the ${EXTEN:x:y} construct:
• ${EXTEN:1:3} would contain 416
• ${EXTEN:4:7} would contain 9671111
• ${EXTEN:-4:4} would start four digits from the end and return four digits, giving
us 1111
• ${EXTEN:2:-4} would start two digits in and exclude the last four digits, giving us
16967
• ${EXTEN:-6:-4} would start six digits from the end and exclude the last four digits,
giving us 67
• ${EXTEN:1} would give us everything after the first digit, or 4169671111 (if the num-
ber of digits to return is left blank, it will return the entire remaining string)
This is a very powerful construct, but most of these variations are not very common in
normal use. For the most part, you will be using ${EXTEN} (or perhaps ${EXTEN:1} if you
need to strip off an external access code).

Here is and example:

When I call 9-555-555512345

in an dial pattern created by my i can do this:

exten => _9555.,1,Dial(dahdi/g0/${EXTEN:1:7)

Here i call over dahdi to the number 555-5555 and the last numbers (can be one or twenty) are deleted and never go to the trunk.

I can’t find any way to get this working over the trunk or outbound route.

Any help will be aprecciated.

Best regards.
