Here is a guide for connecting a Grandstream HT80x to 2talk
It is suggested to use the most recent firmware recommended by the manufacturer.

Please note: Older firmware versions may not autoprovision for security reasons.
Zero touch provisioning:
Configure your router for DHCP option 66. Use the string provided on the device provisioning page as the value for your DHCP option 66 setting.
After obtaining a DHCP lease from your router the IP phone will begin the autoprovisioning process.
Manual provisioning via the web interface:
1. Connect your PC to the same local network as the phone.
2. Connect a phone to a phone port on the ATA, press *** (the star key three times) to
access the IVR menu and wait until you hear “Enter the menu option“, press 02 and the current IP address will be
announced.
3. Input this IP into the address bar of your web browser and browse to this page. You will be prompted to login, the default login username is 'admin' and the default login password is 'admin'.
4. Select the 'Advanced Settings' menu.
5. Input the provisioning URL, obtained on the device provisioning page of your portal, into the 'Config Server Path' field and select 'Apply'.
6. Select 'Reboot' to complete the process. You may need to navigate back to 'Advanced Settings' to select 'Reboot'. Please allow a couple of minutes for the phone to reboot and provision the settings.
