Note The supported version combinations are determined by testing. While other combinations may provide acceptable results to customers, Cisco must test or approve these combinations before they will be supported. Cisco Business Edition 6000/7000 is supported for SIP trunk integrations with Cisco Unity Connection.


Cisco Unified CM support patch (sp) releases have the same compatibility as the base release. In addition, rereleased versions—for example, 7.x(xa) rereleased as 7.x(xb)—are assumed to have the same compatibility unless noted.

Unity Connection service releases (SR) have the same compatibility as the base release.
