[asterisk-users] Cisco SIP 8.5 and 9.0 Issues

[Gerard]

I think you're right JR,
that has been my experience as well, I've run just great with sip 
7.something firmwares for years.. unfortunately those don't support the 
wireless headsets that the people I support want.
My boss really likes the cisco phones, the hardware feels really solid, 
I wouldn't mind testing out a polycom phone though.

The chan-sccp guys are really awesome, it's just not quite ready for my 
office at the moment, it's getting there though, maybe that's a better 
bet. Especially if I can't get SIP sorted out.
