asterisk users - Dec 2005 - Cleaning up CLID on incoming PRI lines

Hey guys,
    Does anyone know of a nice way to clean up CLID on all calls coming 
in a certain trunk? One of our PRI providers drops off the 0, which 
means that matching and 'one-click-call-return' are broken because it 
appends 'half' the Area Code to the CLID (In Australia, area codes are 
prefaced 0NXXXXXXXX).

    At the moment, I have a nasty patch to AMP's 'user-callerid'
macro
that re-writes teh CLIDNum variable to have the correct 12 digits with 
the 0. But because this happens after the initial call pickup, the 
ringing call itself reports the 'bad' CLID.

    Is there a patch or hook I could add to zapata.conf or some way to 
get asterisk to say "Add 0 to the front of all CLID on this ZAP
channel" ?

Thanks all!

Adrian

Adrian,

	I don't know how this will play with AMP, but here is goes:

in zapata.conf, create a new context for calls coming in the PRI in 
question, let's call it "pri-cidfix"

extensions.conf:

[pri-cidfix]
exten => _X.,1,SetCIDNUM(0${CALLERIDNUM})
exten => _X.,2,Dowhatever

or in 1.2:

[pri-cidfix]
exten => _X.,1,Set(CALLERID(number)=0${CALLERIDNUM})
exten => _X.,2,Dowhatever

	I'm being lazy with the extensions and the second priority, but 
hopefully you get the idea.
