We have tested against _lot_ of SIP hardphones. Most of them can speak SIP quite well today, so the decision making process relates to budget, stability, and features.

Cisco telephones have always been the most stable ones. Unfortunately, the most expensive as well. 7905s ship now which are cheaper. Grandstream is certainly the most affordable SIP telephone today and it supports STUN nat-traversal (it ships through sipphone.com). Mitel is a very convenient phone (like Cisco, it features 3-party conferecning, for example), I just sometimes experience voice distortions which are possible caused by the telephone. pingtel is another one of the good-and-quite-expensive class.

We have not been approached by polycom for testing their general-availability phones so I don't have any opinion on them.

There are some other sip phones too, but we either never got them for testing or they are better not worth mentioning. See a list too at http://www.iptel.org/info/products/index.php?category=hardphone&name=Har...

SERusers,

I am working on a pilot for SIP and am planning to purchase a server and install SER on it. I need to purchase several SIP hardphones to test and wanted to see if anyone had any recommendations. Are most of the "SIP compatible" phones out there still proprietary to a particular server? The phone in particular I was looking at is the Polycom Soundpoint IP 600, which won the "Editor's Choice" in a review by Network Computing http://www.nwc.com/shared/printArticle.jhtml?article=/1416/1416f2full.ht ml&pub=nwc . If this will not work, does anyone have ANY hardphone recommendations? Polycom says their product has only been tested with Broadcom's SIP server.

I apologize for being such a newb...I am still trying to read up on SIP and understand the big picture. I appreciate any help or feedback.

Thanks, Scott
