Use Polycom, but if you really must use cisco phones, downgrade to 7.5.
I've got a lot of 79xx phones out there and 7.5 is the last stable release
as far as I'm concerned.  It just seems to work, no periodic reboots needed,
or any other quirkiness like with the newer firmware's.  The feature set is
not robust, but it is reliable with Asterisk.  Keep in mind, Cisco has no
incentive to make their SIP firmware work with any other platform other than
there servers so I don't really expect it to work properly if at all with
Asterisk.  7.5 is the only firmware version that I deploy on a few hundred
units and works fine.

Good luck.
