VoIP Ports
IP Signalling Port:
The default IP signalling port is 5060. If you need to choose another
port, enter a value between 1024 and 16556.
Starting RTP Port:
The starting RTP port for TalkSwitch is 6000. From this starting point,
TalkSwitch needs 4 ports for each TalkSwitch unit. RTP ports are evenly
numbered from the start port. 6000, 6002, 6004 and 6006 are needed for
the first TalkSwitch unit on a LAN and 6030, 6032, 6034 and 6036 are
used for the fourth unit.
These are the ports that this TalkSwitch system listens on as opposed to the
port it needs to communicate with at the other end.
Example: If your IP server at another location uses port 5061 instead of
5060 for signalling, you do not set this port to 5061, you need to include
the port number in the address specified in the VoIP Configuration section
of the software.
Example: Proxy Server Name: 222.234.432.234:5061
