Connect any digital phones to their appropriate DS ports. These phones may need to upgrade their firmware to match that supported by the IP Office core software. The appropriate firmware is supplied with the IP Office Manager software and copied onto the System SD card for IP500 V2A systems.

The phones will automatically load the firmware from the IP Office system if necessary.

The upgrade process takes approximately 10 minutes during which time the phone will display a warning. The phone should not be disconnected during this process.

Once the phone connected to a port has been upgraded, the IP Office will not check whether the phone on that port needs to be upgraded again except following a system reboot, i.e. multiple phones cannot be upgraded by swapping the connected phones on the same port.
