Essential Edition mode is supported on IP500 V2 controls units.

• In Essential Edition mode, the IP500 V2 can support up to 384 users using analog, digital, and IP phones and applications.

• For voicemail, Essential Edition supports embedded voicemail using the Avaya IP Office SD card installed in the IP500 V2 control unit.

• In addition to an Essential Edition license, the Essential Edition system may also require additional trunk, IP extension and embedded voicemail licenses depending on required features and capacity.

• An Essential Edition license is a prerequisite for Preferred Edition, but not for running an IP500 V2 control unit in any of the other IP Office modes.
