Optional – configure Zultys ZIP49G “door phone” features

Optionally, you can enable “door phone” integration features on a Zultys ZIP49G desk phone.

In MX Admin open the device profile assigned to your ZIP49G phones , go to “Advanced” tab and select “Custom configuration data” in a drop down box .

Enter following configuration in the text area:

features.doorphone.1.autopreview.enable = 1
features.doorphone.1.display_name = Video Intercom
features.doorphone.1.full_screen = 1
features.doorphone.1.phone_number = 300
features.doorphone.1.send_video = 0
features.doorphone.1.videopreview.enable = 1
features.doorphone.1.unlock_pin = 

Change features.doorphone.1.phone_number value to an extension of a previously created user that the GDS3710 video intercom is assigned to. This will allow the phone to detect intercom call and display a video preview. NOTE: this only works if intercom is configured to dial a user extension, and will not work for groups.

Optionally, set features.doorphone.1.unlock_pin value to match the Momentary Open code you’ve set up under Remote PIN to Open Door in the GDS3710 Intercom. This will allow users to use a “door” icon on the phone screen to open a door , instead of dialing code on the dial pad

Once you’ve applied new settings , update your ZIP49G phones – use the “Update..” button at the bottom of the Managed Devices window
