[asterisk-biz] Service request: Simple issue on a2billing.php

[Ricardo Martins]

Dear friends, I need a simple customization service for A2Billing.

I have to execute an Asterisk Set command rewriting the callerid(num) 
variable with the callerid(name) value just before  the a2billing.php 
dials to selected trunk. The Asterisk dialplan command would be 
"Set(CALLERID(num)=${CALLERID(name)})

I need to write this on AGI/PHP language at the right position inside 
a2billing.php script.
Do anybody know how to do this?

Pls send me the price/service offer in PVT. We use Asterisk 1.4 and 
A2billing 1.3.4.

Regards, Ricardo.
