[Asterisk-Users] Asterisk hardphone

[Chris]

I've got Asterisk up and running nicely using a couple of different softphones.  Audio quality is suffering a bit due to the hardware that I am working with. So I tried to use a Polycom hardphone but the politics is enough to give you a headache.  Polycom seems to support SIP only if you buy it thought their vendors.  So I'm looking at a Cisco phone.  Has anyone successfully implemented Asterisk with a hardphone? Which one?
