Realtime certainly works with SIP users.

And yes, SIP subscriptions are lost in the current code. In 1.0, the
support for subscriptions was very poor so it wasn't used. In 1.2, a few
of us *non-Digum* developers enhanced it quite a lot. A community
effort, not related to Digium at all. That's why SIP subscriptions is
now a useful feature in Asterisk.

In 1.3, because we made subscriptions very popular, we have to rewrite
the whole subscription system in order to support a large quantity of
subscriptions and new features users now want, like shared line
apperances and call control.

A lot of the work with Asterisk is done by non-Digium developers, in
many cases paid for by Asterisk users that wants to enhance Asterisk to
better support their business but can't or don't want to develop in house.

Digium adds quite a lot of quality control, especially now when they
have a team of testers working with the Asterisk Business Edition. I've
also started to take Asterisk to the SIP interoperability testing events
to further enhance the SIP support in Asterisk.

If you want something to change, please do not go out saying "this whole
product is crap, since feature yyy does not work as expected and Digium
stinks by the way". We are very open to discuss bugs and missing
features, as the product is being enhanced. The Asterisk.org developer
community is very large, as you can see if you visit the bugtracker and
check who is really contributing.

Visiting the bug tracker might be a good idea anyway, that's a good
place to report your bugs.

Good luck with your continued work with Asterisk!
