CommuniGate is claiming that the demonstration is the first milestone in building large-scale, standards-based communities of VoIP subscribers, since traditional telecommunications, cable, and wireless providers often support over 50 million subscribers. The benchmark simulation was conducted to provie cost-effective scaling by just adding notes, using either virtualization or physical additions of servers to the running cluster as needed.

Call load generation topped out at 1,000 SIP calls per second with up to 192,000 unique registered user-agent enpoints driven by a Navitel device for inbound calling. Simultaneously, the open source "sipp" SIP load generator was used to generate additional outbound calls.

Using a virtualized cluster on a single Superdome system, the benchmark team discovered that the CommuniGate SIP Farm and F5 supplied hardware continued to perform within required QoS until no further load could be generated by the test environment available. Future tests will use a fully-equipped Navtel chassis to increase available SIP load capability.
