Free online fuck chatting website no credit card required - Polycom stuck on updating initial configuration
The Polycom 501's do have more and easier-to-get-to functionality than the GXP-2000's, and have a more professional look and feel (and a great speakerphone), but the most notable downsides of the 501 are its awful, obtuse and slow configuration interfaces.
Note that this article is quite lengthy as the entire process is described in detail, accompanied by various log entries and other examples.
There is good information on this site about setting up a Polycom phone to work with Asterisk, but it's rather spread out and unorganized, so I thought I'd take some time to get it all in one place.
These instructions apply to the 501 models, but I believe they would adapt well to other Polycom models.
I also don't go into pushing out configurations from XML files on a TFTP server, but it may be the way to go if you're doing more than one phone.
Now that the 5.0.1 maintenance release is available then this and all future releases can be handled natively by the Lync server.
