Performance & High Availability

NATPass™ performance depends on processing power of hardware utilized and number of call setups per second. NATPass™ is an extremely optimized and fast SBC. It can run ~150 call setups per second on a dual CPU server. High end quad with dual core should be able to run in range of 100,000 or more sporadic users like soft phone accounts to about 30,000 static fixed phone users. Capacity will depend on server architecture as well as type of usage of network (residential vs. call center). The use of a dual Pentium server at 3 GHZ with a fast FSB and 2 GB of RAM is recommended for large deployments.

DNS SRV records are supported by NATPass™ allowing redundant or active-standby type of proxy servers. When configuring high availability NATPass™ application can run on an active server and automatically switch over to a standby server when the main one fails.
