[asterisk-users] dialplan help

[vivek at staff.ownmail.com]

Dear friends,
  Does anyone know how do i convert hex to int in the dialplan. I want to do this:-
Take the sip call-id in hex, use CUT to extract the first part , and convert it to an int. But the math function ony takes arguments as int. Can anyone suggest how to do that?
eg:- 
exten => _X.,n,Set(sipcid = ${CUT(SIPCALLID,-,1)})  ---> evaluates to E305CEC5
I want this hex value in int. But i cant think of a clean solution. 
Please help.

Thanks in advance.





With warm regards.
