Supported protocols

•  H.323/H.460

Supported OS

•   Server: Red Hat Enterprise Linux 4, CentOS4
Red Hat Enterprise Linux 5, CentOS5

•   Client: Windows XP, Windows Vista

Firewall/NAT traversal

•   H.323 relaying on Client-Server communication paths.

•   Client located in private network, Server in DMZ
Data Center or POP

•   Only ‘outbound’ initiated connections on configurable
port or port range

•   TCP or mixed TCP/UDP relay paths (e.g. TCP
Port 8080, TCP/UDP port 8081-8082 etc)

Security

•   Consistent with existing enterprise firewall policies.

•   Communication restricted to small set of controllable
firewall ports

•   Only authenticated Clients connect

•   Strong encryption with support for CBC and EBC
modes of AES 128, 192 and 256 bits

Minimum server Hardware specification

•   Intel Pentium4 2.8GHz, Xeon 2.13GHz processor

•   1024 MB RAM

•   100Base-TX NIC

•   100MB disk space

Performance and scaling

•   Client and Server added latency < 8ms

•   Single Server: 50 concurrent traversal of 384kbps
calls (dual processor system)

•   Scales linearly by adding additional servers
