[SR-Dev] path parser support in sr

Hi, one module that is still not works with sr is the registrar module. In order to compile path support (RFC 3327) is necessary. The path module already compiles, but some necessary functions in the parser are missing. I've digged a bit in the archives, a few years ago there were some proposals about path support in SER, but i was not able to found this in the current tree. I found something in the roadmap for SER 2.1. How should i progress in this regards? Just try to porting the missing parser parts from kamailio, or is there perhaps a own implementation in SER somehow? Henning
