'interconnecting' - what do you mean by this? I would imagine this is a
simple gateway function so I'm not quite sure to what extent you want to
interconnect? maybe you can elaborate?

I don't think SR/Kamailio is the correct place to build a gateway. For a
University POC, maybe, but I would imagine it would be far better to build
it as a separate AGCF entity with an IMS stack (possibly something like
doubango - very good IMS stack IMO).

that is the main goal of my project.

3.2 won't make a diff for IMS extensions, however, we are now really close
to putting in another branch with the latest stuff we are doing with
kamailio and IMS. Just give us a few more days.
