Getting SIP headers through Asterisk manager

Question

I am trying to elaborate SIP messages coming to an Asterisk server and edit them on the fly using Java.

AMI is supposed to work fine with that. Although I can't send any SIP messages though the socket, cause every-time I tried to edit chan_sip.c the server breaks down. So I haven't find a way to access this information from other classes of the manager. I don't want to save those information to a file or database cause this will delay the whole process.

Using Kamailio is not an option cause I want to make a comparison of both solutions so I need Asterisk.

Is there any path I should follow to get this done? I can't figure why editing chan_sip.c bothers Asterisk making him nonfunctional..

Seams like no way with your qualification. Task seams really complex for me(i have more then 10 years experience, including asteirsk internal and c/c++ programming).Try do that using dialplan only
