Appendixc; Network Ports - Altigen ACM 6.7 Administrator's Manual

If MAXCS 6.7 is behind a firewall/NAT router, you must open TCP and UDP ports
according to this table:
For external VoIP connection through a firewall
Remote AltiGen IP phone/IPTalk to phone service
Remote AltiGen IP phone firmware download (TFTP)
Extension global appearance
VoIP RTP Port (Voice Stream) for SIP and H.323
SIP Tie Trunk from other AltiGen systems
SIP Trunking Service from carrier
H.323 Tie Trunk
H.245 (Media Capability)
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
Y = BasePort + Total IP codec channels x 2
For a multi-chassis system, you need to enter multiple ranges:
