The TechNet Web site did not provide a deep-dive on details of what the new Voice CAL includes, but in general it has all the current voice functionality in the Enterprise 2007 R2 CAL plus something entitled "enterprise ready voice -- PBX Replace Voice," Branch Survivability, E-911, PSTN Failover and Analog Device Support.

Rumors of a new Voice CAL for OCS first surfaced in February, but a blog posting on a TechNet Web site called said that a news license will be required, and introduced a promotion to get users to commit to the new Voice CAL now.

The promotion will provide free access rights to the 2010 and 2011+ versions of the Voice CAL to any company that has SA coverage as of June 30, 2009 on their OCS Enterprise CAL or their Microsoft Enterprise CAL Suite.

Users will have to stay current on SA through the two releases of OCS.

The promotion offer also has the option of free access to only the 2010 version of the Voice CAL to those that purchase after July 1, 2009 an SA contract for their OCS Enterprise CAL or their Microsoft Enterprise CAL Suite.
