The model update feature under web UI-> PBX-> Zero Config-> Model Update, How can I use it?
In model update, the available model packages such as gs wave, surveillance and etc are located in a remote server. When there is an package update or new package available for a grandstream product, it will be uploaded in the remote server for user to download. UCM shows the available packages in model update web page. The "manual upload package option" under the same page with Model Update is for users who are using UCM in a private network that Internet access is restricted. They will not be able to get packages by downloading and installing from the remote server. Therefore, users that placed their UCM in a private network, please contact Grandstream customer support to get the model package and upload it manually through web interface.

When I have two SIP trunks registered to the same provider, the incoming calls to both trunks are always received from the first trunk. Why?
If this issue happens to your UCM6100, please check your inbound route configuration and make sure the DID pattern is unique for the inbound route assigned to each of those two trunks. Once the inbound route has unique DID pattern configured, the issue should be resolved. This is because the calls from both trunks have the same IP/port. In the cases when "To header/Request line" doesn't always have the extension that the UCM6100 is registered to, we will need different inbound route DID pattern to differentiate them.
Which IP phones are supported by the UCM6100 series?
All current Grandstream IP Phones are certified to work with the UCM6100 series and can also be configured via the 'Zero Configuration' feature. Additionally, we have tested basic functionality with our UCM6100 series on Cisco, Polycom, Aastra, Snom & Yealink SIP-based phones. The UCM6100 series is a SIP-based IP PBX which adheres to SIP standards and therefore should support SIP-based functionality on most SIP IP phones available today. The UCM6100 series runs on a customized version of the Asterisk OS and users can also refer to Asterisk's list of supported IP Phones and Asterisk configuration notes for specific hard phones and ATAs for a more detailed list.
