Yes, it's the "Skinny Client Control Protocol", aka "Skinny" or "SCCP".
There are 2 Asterisk channel drivers supporting this protocol:
- chan_skinny, which comes with asterisk
This one is quite stable but supportsy nearly nothing except placing or
receiving single calls.
- chan_sccp, from http://theo.me.uk/pages.shtml?page=sccp
This one may crash asterisk if some very odd skinny phone tries to
register. (The 7912 may qualify as "odd", as it's not officially
supported right now.)
However, it does support some nice features (soft keys, multiple calls
don't crash *, ...)
Some features like intercom (paging) or speed dials don't seem to be
completely implemented, yet. But the author seems quite responsive to me
and the code is easy to read/update.

Sure, but some development work still has to be done, first.
