asterisk users - Apr 2004 - Asterisk + Cisco 7920 + chan_sccp or chan_skinny

Greetings,

I have seen a few postings in the past regarding the interop of Asterisk and
the Cisco 7920 WiFi phone.  To date, I have not seen a definitive method to
getting the phone working.  Assuming someone has this actually working, can
that person step up and answer these questions.

1) What Channel is it working with (chan_skinny or chan_sccp)?


2) If code was used that is not a part of a current Asterisk CVS release,
exactly where did that code come from?


3) What specifically is needed in the config files (skinny.conf or
sccp.conf, SEP<MAC>.cnf.xml etc)?  An example would be great.


4) Are any specific firmware versions required for the Cisco 7920 for the
interop to work?


5) What codecs have been successfully tested?


6) What is the proper structure for the TFTP server root and files?


If anyone can step up on this one and provide information, I would be happy
to put it all together in a fully documented HOWTO so that anyone else
attempting this configuration will have a clear and concise guide.

I don't have 7920, so fail your first requirement, but I do know that the
7920 is reported to work with chan_sccp as modified by Lambda Solutions
(their original mods were specifically to provide support for 7920, but
added other features as well such as multi line registrations for
79[46]0).  I remember seeing list messages saying that 7920 was completely
unsupported by either chan_skinny or the original chan_sccp, and even with 
Lambda's chan_sccp mods only basic function was available.

Where you would get chan_sccp nowadays though is a mystery, as its last
known download location seems to have disappeared from the net (well, the
domain appears to have been appropriated and is being used for something
else)...

I am using one version of their chan_sccp with a 7960, and can vouch for
its functionality there.  If you strike out finding an up-to-date version
on the net, I can send you a tarball.

If you have not already, check the list archives -- it might give you an 
idea of where development got to.
