Product Feature
Product Specification
●
Support for capacity warnings for users and administrators
Network
●
Support for Domain Name System (DNS) addressing
●
Support for IPv4 and IPv6 simultaneously
●
Support for IPv4 and IPv6 translation services
Scalability and Capacity
Single VCS capacity:
(appliance or small and
medium virtual-machine
deployments)
●
The capacity of one Cisco VCS (appliance or small and medium virtual machine) follows:
◦
Up to 2500 registrations
◦
Up to 500 nontraversal calls
◦
Up to 100 traversal calls
◦
Up to 1000 subzones
Single VCS capacity:
(large virtual-machine
deployments)
●
The capacity of one Cisco VCS (large virtual machine) follows:
◦
Up to 5000 registrations
◦
Up to 500 nontraversal calls
◦
Up to 500 traversal calls
◦
Up to 1000 subzones
Clustered VCS capacity
●
Up to six VCS appliances or virtual machines can be clustered to increase capacity and provide redundancy.
●
Clustering increases the maximum registrations, traversal, and nontraversal calls by up to four times.
Microsoft Lync Interworking
Capacity
The maximum number of calls interworked to Microsoft Lync is 100. It is highly recommended that a separate VCS
Control server is deployed for use as a dedicated Microsoft Lync gateway.
