[SR-Users] Kamailio as a front end?

I am looking for something that would act as front end to various SIP PBX systems. I am using Asterisk, but compatibility with others might be necessary. What I want to do is pass subscribe requests with certain content types to an external program (written in Java) and the rest onto the SIP PBX. Can Kamailio do this and if so, is there some example config files somewhere that I can look at to get started?
