klaus,
there are tons of those. in the beginning i tried to keep track, but it
looked like no-one else in sr community was interested in presence, so i
gave up and started to use opensips as my presence server. opensips too
has its shortcomings, such as lack of oma support in xcap authorization,
but looks like it is being active developed on. it would take couple of
sr people full time for at least half a year to catch up.
