Configuring the firewall for voice data

In order to pass through a router's firewall, voice data received by your
network must be mapped to the appropriate TalkSwitch unit. TalkSwitch uses
UPnP (Universal Plug and Play) to automatically map firewall ports in order
to forward VoIP data. If your router supports UPnP, ensure that it is enabled
(see your router documentation for configuration details).
If a router does not support UPnP, you will need to configure the router to
map specific ports to TalkSwitch. The following describes which ports to map
to TalkSwitch:
• To allow SIP Signaling data to be forwarded to TalkSwitch, firewall port
5060 must be mapped to the TalkSwitch unit known as the local proxy.
By default, this is the lowest numbered TalkSwitch on a LAN. The IP
Configuration page of the TalkSwitch configuration software indicates
with an asterisk which TalkSwitch unit is the local proxy. SIP Signaling
uses UDP.
For example, in a 4-unit network, firewall port 5060 (UDP) would need to
be mapped to the IP Address of the TalkSwitch unit ID #1.
• To allow voice traffic to be forwarded to TalkSwitch, corresponding ports
must be mapped to each TalkSwitch unit. The following tables show the
firewall ports to map to each TalkSwitch unit on a LAN.
The tables show the default port numbers. For instructions on re-
assigning these numbers, contact TalkSwitch Technical Support
