It provides a similar desktop experience as the Partner ACS. Partner Version provides the bulk of the feature set that the current Partner ACS R8 supports; plus integrates enhanced features from the IP Office Essential Edition platform, such as Mobile Twinning, Visual Voice Mail, 64-party Conferencing, SIP Trunking, Full PRI/T1 and more. It also includes Embedded Voice Mail; providing a 2-port Automated Attendant (upgradeable to 6-ports) and voice mail coverage activated for all telephones.
