[SR-Users] OMA/RCS Presence compliance

[Carsten Bock]

Hi Alex,

I believe that statement goes back to me, but unfortunately, i was wrong.

While Kamailio implements a lot of functionality to be OMA/RCS
compliant, we are still missing some features. The best example is
probably, that 3GPP standards request, that MSRP sessions are
Store&Forward rather than direct requests (in the "Big yellow book on
IMS" by Camarillo & others* it's stated, that you should use an
MSRP-Relay; but that information is unfortunately outdated). But
that's only one example from many.

Also typical RCS-Clients do for example a partial update on XCAP
Lists, which is afaik not supported by Kamailio (yet). A major vendor
pointed out, that the SIP-Part of implementing RCS was not the biggest
task, but rather the XCAP stuff...

I (still) believe, if someone would put some effort into it, it could
be achieved in reasonable time. Kamailio has all the necessary
starting points to do so (MSRP-, XCAP-, SIP-Support), but we would
have to go that extra mile.

Kind regards,
Carsten
