IP Office supports the 1120E, 1140E, 1220 and 1230 telephones. In most cases these phones are redeployed from previous Nortel BCM or SIP system and need migration from their existing firmware to Avaya IP Office SIP firmware.

The additional steps for the firmware migration options are detailed in the separate IP Office 1100/1200 Series Phone Installation manual.

This series of phones is not supported in IP Office Subscription mode.
