I've tested transfer, voicemail, and MWI. Conference should work have
I haven't tested it.

There are two SCCP modules, but I haven't heard about anyone using
7940/60s with SCCP and Asterisk. The phone works very well with SIP.

To the best of my knowledge, the phone's internal menus aren't
customizable at all. However, the 'services' button on the front panel
works just like a menu button and fetches XML content over HTTP. You
can get a good overview of the syntax and possibilities from

In addition to the service button, you can also change some of the
content reached from the directory button. With SIP firmware v6.3,
there are 5 menus available from the directory button:
missed calls
incoming calls
outgoing calls
personal directory
external directory
(I may have the wording and order slightly wrong, I'm not in front of
my phone right now). The first 3 menus are built into the phone and
are maintained automatically. You can copy names and numbers from
these three into the personal directory. I assume that the personal
directory is limited to ~32 entries, but I haven't tested it. Finally,
the external directory option fetches XML from a web server, just like
the services button. You can use it to implement a shared phone
directory.

Yeah, the documentation is kind of sparse. Google can help. Here are
a couple useful pages that I've tracked down:
