Very rich feature software, allows nearly all feature for Enterprise. Very good provisioning, excellent support from Cisco TAC. Plenty of hardware endpoints available. MRA (mobile remote access) allows remote users to connect to enterprise very securely. Good integration with other Cisco UC products such as Presence, Meeting server, Unity Connection etc. Stable and controllable telephony. Good documentation. Review collected by and hosted on G2.com.
Expensive. Very high requirements to amount of virtual machines and their resources. Proprietary, not very friendly to 3-d party devices. Jtapi API for 3-d party integration looks a little bit obsolete. Review collected by and hosted on G2.com.
