The Avaya IP Office 400 Phone 16 V2 provides 16 additional analog station ports for your Avaya IP Office system.


IP400 Phone 16 V2 Features

  • Provides an additional 16 Plain Ordinary Telephone (POT) ports for use with analog telephones
  • Changes from V1 to V2: The Phone V2 uses an earthed 3-pin 60W external power supply unit. With IP Office 3.1, the message waiting indication (MWI) on each POT port can be configured for None, On, 51V Stepped, 81V, Line Reversal A or Line Reversal B. On uses the default determined by the system locale. POT ports on a Phone V2 module can additionally be configured for 101V operation. The ports do not include a ringing capacitor. Therefore for phones where this is a requirement, connection should be via a Master socket containing ringing capacitors. The DTE serial port on the rear of the module has been changed to a 9-pin D-type socket.


  • IP403, IP406 V1, IP406 V2, and IP412
  • IP500 running R4.2 or earlier; Professional Edition is required
  • IP500 running R5.0 or higher
  • IP500 V2 running R6.0 or higher




For IP Office 400 systems To make the installation easier let me know what release your Processor is at and I’ll set the expansion module to the same major release such as 3.2 or 5.0.  By doing this your processor should be able to see it and this will make the installation much easier especially if this a swap out of an expansion module that has died.


To find the release of your processor you will need to log into your IP Office Processor using Manager and go to “Control Unit” and click on the processor and look at the version and let me know what version that is.


For Expansion modules to be recognized and seen by the Processor power must be provided first to them and be connected with the Shielded Cat 5 cable to an available Expansion Port on the Processor you are connecting it to and have a green light.  After the Green light is on the Expansion Module – Then power up the Processor if power is lost during the upgrade the expansion module will be red lighted and need to be repaired – DON”T LOSE POWER DURING AN UPGRADE!!!.


Also sometimes you must then do an upgrade of the Expansion Module to finalize it on the system and to be working.  The release version apparently does not always need to match that of the processor based off of my experience.   Also on the IP Office if this is an upgraded 500 System up to or beyond release 8 you are going to put it on for Expansion Modules to work you must have the Large Upgrade license for over 32 users and External Expansion Modules (the small upgrade license only allows for up to 32 users and no external expansion modules) – so make sure you have the Large Upgrade License.
