[Asterisk-Users] Cisco 7960s and skinny

[Andy Hamilton]

Anton:

Yes, the whole legally licensing the phones from Cisco is a major drawback.
I just compiled and install the chan_sccp-mayday CVS snapshot.
It works like a charm (thanks Julien!). In fact, I did some dialing
and redialing to my 7960 (SIP) from my 7910 and the 7960 ended up
needing to be rebooted. I was quite pleasantly surprised; the
7910/chan_sccp seemed to be having a field day.

Here is what I have found for the 7910:
-> Hold button works (a little weird when more than one call)
-> Line button brings up the line
-> Transfer button doesn't seem to work
-> Msgs button doesn't seem to work
-> Conf button doesn't seem to to work
-> Forward button doesn't seem to work
-> Speed1 doesn't seem to work
-> Speed2 doesn't seem to work
-> Redial works

Hope this helps.
