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.

Firewall ports* required open for VoIP communication with TalkSwitch

Description	Type	Unit 1	Unit 2	Unit 3	Unit 4
Voice traffic	UDP	6000–6006	6010–6016	6020–6026	6030–6036

*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.
