Network Ports
If MAXCS is installed behind a firewall/NAT router, you must open TCP and UDP ports according to this table:
For external VoIP connection through a firewall TCP UDP
Remote IP phone/IPTalk to phone service
10032
10064
5061
10060
Remote AltiGen IP phone firmware download (TFTP) 69
Extension global appearance 10066
VoIP RTP Port (Voice Stream) for SIP
From X to Y
(See note
below)
SIP Tie Trunk from other AltiGen systems 10060
SIP Trunking Service from carrier 5060
Polycom phone service
80
443
When adding additional combo licenses, the system will also increase the RTP ports it uses and will use these
new ports. If these additional ports are not added to the firewall, then calls will not have audio.
Note: An easy way to find out the RTP/TCP port range(s) for SIP is to look in the MaxAdmin View > Current
Resource Statistics
window. 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
