Part Number 700417207, the Avaya IP500 Office Server, has a greater VCM channel capacity and performance, the IP Office 500 is the most suitable of the IP Office range for IP Telephony applications. It also provides an entry level offer into the IP Office family through IP Office Standard Edition software (included with the of the IP500 Base Unit).

 The IP Office 500 is a stackable unit with an optional 19" rack mounting kit and an optional wall mounting kit for smaller configurations. By default the IP500 control unit runs a subset of full IP Office functionality called IP Office Standard Edition. In this mode the IP500 is restricted to a maximum of 32 users (24 Digital) in the base control unit with no expansion. Supported options include Embedded Voicemail, Phone Manager Lite/Pro/PC Softphone, SoftConsole, TAPI, SMDR, CBC, SIP trunking, mobile twinning, VPN Phone and IP DECT, as well as licenses for voice networking (H.323 or SCN). IP Office Standard Edition does not support advanced applications (VoiceMail Pro, CCC, Conference Center, etc).

  This restriction can be removed by adding an IP Office Professional Edition Upgrade license to the configuration. By purchasing the upgrade license from Standard Edition to Professional Edition, additional functionality is enabled. This includes the ability to expand the system using up to eight external Expansion Modules, allowing the IP500 to support a maximum of 272 phones through a mixture of analog, digital or IP handsets.

 If additional analog trunks are required, these can be aggregated in groups of 16 via the use of external analog expansion modules . Note that the Professional Edition also enables the licensing of advanced applications such as VoiceMail Pro.
