Thanks Darren for this info. We performed some updates yesterday on several GXP-1450 telephones. After getting the run around from GS, we finally were able to learn that they only provide the hosted firmware updates for the older phones and not the 21xx series and have no idea when they will. On the GXP1450 all we needed to do was add firmware.grandstream.com in the Firmware Server Path field and set Upgrade Via HTTP, then rebooted the phone. After +5 minutes it upgraded fine. For the 21xx phones (before knowing they didn't have a firmware site), we entered the same firmware.grandstream.com and rebooted phone and nothing would happen. No error, no reports, it just didn't do anything. After contacting GS support someone finally told us the info that we had to create our own TFTP site and place files there, which we have. So, this was a major issue for us and it seems to have a path to resolution, once we update all the phones. We are very excited when 2600Hz adds GS auto provisioning..... soon we hope.
