Last I looked (around February) there were some things in Kamailio presence that aren't in OpenSIPS.

For example, the separate notifier processes in both presence and rls (I believe one may have been ported across now by Saul - but not both). There are also extensions relating to the built-in XCAP server (particularly in presence_xml and rls) that are in Kamailio and not OpenSIPS. I know that there are some specific RLS fixes and features in Kamailio that only work when you use the built-in XCAP server. I also made some enhancements to the way pidf-manipulation is handled in Kamailio that I do not think have been ported to OpenSIPS.

Basically, while OpenSIPS presence may be more advanced in some ways I am quite sure it is less developed in some others. Having spent a lot of time over the course of around 18 months doing work in Kamailio presence I would strongly resist any attempts to junk what is currently there because I know that I need a lot of the stuff that is in the Kamailio implementation. I don't currently have the time to develop it further at the moment either.

I think the "junk them and replace with opensips" approach would be a disaster.

Regards,

looks like kamailio presence and especially rls is lagging behind in development as compared to opensips. it properly handles the escapes that i had trouble with, support external references in presence rules, xcal-diff, etc.

what should we do about kamailio presence modules? junk them and replace with opensips ones or implement the missing stuff ourselves? i personally don't have resources for the latter.
