Hello,

if you use devel version (git master branch), you have sip.instance handling according to rfc5627 - GRUU. It is in my plans to review 5626 and see what can be implemented before 3.3.0. It keeps one contact address per +sip.instance.

Older versions have sip.instace handled by modules_s/{registrar|usrloc} to some extent, I guess based on some draft in the past.

Cheers, Daniel

Hi,

I'm just wondering if there has been any type of work to implement any part of RFC 5626, particularly the registrar server code?

Lumicall now generates a UUID at install time, and sends that as sip.instance in the Contact header. It always sends reg-id=1 (only trying one proxy at the moment).

Although this is not a full implementation of the spec, it seems to be sufficient for eliminating extra Contact records in the repro registration server (from reSIProcate). However, I've noticed Kamailio doesn't seem to understand this parameter yet.

Regards,

Daniel
