Network Ports

If MAXCS 6.5 is behind a firewall/NAT router, you need to open TCP and UDP ports

according to the following table:

Note: An easy way to find out the RTP/TCP port range(s) for SIP and H.323 is to look in

MaxAdmin View > Current Resource Statistics. All the ports are listed in the

Local Ports column.

Alternatively, you can figure the port range in the following way:

When MAXCS or Softswitch is running on a non-Windows 2008 system,

BasePort = 49152

When MAXCS or Softswitch is running on a Windows 2008 system,

BasePort = 49664 (This is because Windows 2008 has some system services use

ports in the 49152 range.)

For a single chassis system:

X = BasePort

For external VoIP connection through a firewall TCP UDP
