Hello,
I'm considering using Asterisk with some type of Cisco phone, and
currently
considering either the 7940 or 7960 because of its more-complete
functionality
(compared to the 7905).
I'm currently wondering:
Do all the expected functions (transfer, conference, voice mail,
message
waiting indicator, etc.) work normally with Asterisk over SIP?
I've tested transfer, voicemail, and MWI. Conference should work have
I haven't tested it.
What caveats are known about using these phones with SIP, as opposed
to
Cisco's proprietary SCCP? If an SCCP module is available for
Asterisk,
how functional is 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.
How customizable are the phone menus while using SIP (or if a SCCP
module is available, using SCCP)?
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
http://www.cisco.com/univercd/cc/td/doc/product/voice/vpdd/cdd/3_0/
phsvcdev.pdf
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.
Cisco doesn't seem to have much documentation online about using these
phones
in SIP mode, so if anyone is using these phones now, I'd appreciate
hearing
about your experiences.
Yeah, the documentation is kind of sparse. Google can help. Here are
a couple useful pages that I've tracked down:
