I am so frustrated. I have spent the better part of a day trying to provision my new Polycom SP IP 321. I have read page after page on the Internet. It is all so confusing. Edit this file. Edit that file. All I want is for the SP 321 to show up on the Endpoint Configuration page, and to properly configure the phone. I have downloaded the files from the Polycom web site, but I have no idea what to do with them. I am running Elastix 1.6-12 in a virtual machine, using HyperV on a Windows Server 2008 R2 host. My DHCP is Windows Small Business Server 2008. I see all kinds of options to add to my DHCP server, but Windows doesn't have those options that I know of. I am really lost, and don't know what to do about it. When I try to set up my phone, all I have for phones available are IP 301, IP 320, IP 330, and a bunch of higher end phones. How do I get my IP 321 in the list? How do I get the phone to understand where to look for the files? I need explicit instructions, as this is my first time.
