Chorus: How to re-program a device

First, factory reset the device:

​​Follow these steps to perform a factory reset of the Unify phone:

1. ​​Hold 289 keys down at the same time
2. ​​The phone will then ask for a reset password
3. ​​​​Type 124816, press OK, and the phone will reset back to asking for the terminal number

Next, enter the university extension number (terminal number), in the format:

    44186527xxxx

    44186528xxxx

    44186561xxxx

Please ensure that the correct number is keyed in, as entering a wrong number will require a factory reset for the phone.

This is for a device that has been previously configured to swap and/or add extensions - for new Gigasets please see the next section.

Find the IP address of the base.  This can be done by tapping the blue button in the middle of the base which will page any paired handsets, displaying the IP address.

Please use Chorus support to send the IP address of the base to the Chorus team, with the required extension changes.
