My IP430 Does, the IP650 did, and so does the vonage adapter. I was just in awe over the way the 650 handled it. Gotta remember its digital, so when it comes to quality from the provider its either perfect or it breaks up. Like digital TV, crystal or Nothing. How it sounds to you depends on the phone.
To save you some time, configure it over the web interface just hit the phones ip in a browser. If it asks for a user name and pass the default is Polycom (note the capital) and the pass is 456
Make sure the provider will let you talk sip to them. no IAX unless your running a PBX. I work phones a lot, And i love the polycom's, If you have a problem post it, i will try to help. The only thing you might run into is a registering issue.
If i had $300 right now i would buy a 650, I have been wanting one for a long time. And working with them all the time at work is just a slap in the face.
