5.2.3.2 Confirm router/firewall path 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 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
toTalkSwitch:
• 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 window of the TalkSwitch software indicates with an
asterix which TalkSwitch unit is the local proxy. SIP Signaling uses UDP.
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 table shows the
firewall ports to map to each TalkSwitch unit on a LAN.

*Default port numbers. For instructions on re-assigning these numbers, contact TalkSwitch Technical
Support.
• If you plan on configuring TalkSwitch remotely, you will need to map
port 9393 (Type: TCP) to the TalkSwitch unit that is being configured.
Configuration is done using TCP.
Description Type Unit 1 Unit 2 Unit 3 Unit 4
Voice traffic UDP 6000–6006 6010–6016 6020–6026 6030–6036
