New Grandstream firmware has been released, you can go to the Grandstream web site to find directions and a link to their TFTP server. This will allow you to update GXP-2000 phones to firmware version 1.1.4.18. This is now the officially supported firmware when used with Talkswitch phone systems.
We have found the new firmware provides superb call quality. Also, customers that used to have some ECHO from the phone due to network issues (rare), no longer do. Overall, a solid release. I (the poster) now use this phone exclusively in the office as it is a very easy to use phone with excellent call quality.
