office market is the Linksys BEFSR81. It can be configured to provide prioritization
of the voice traffic on the broadband connection to ensure that voice traffic gets
through. It also supports DHCP, UPnP and VPN Pass Through.
TalkSwitch uses UPnP (Universal Plug and Play) to automatically configure port
forwarding VoIP ports, and receive updates whenever the WAN IP address changes so
that it can properly update SIP messages.
2.6.3 The Local Area Network
To share voice and data properly, your network requires an Ethernet switch. A switch,
in effect, isolates the Ethernet ports from each other and only passes through traffic
intended for the device connected to that port, which ensures that data traffic doesn’t
compete with voice traffic. For example, the Linksys BEFSR81 router has a built-in 8
port switch which is perfect for a LAN supporting both TalkSwitch units and
computers. If you’re not certain whether your equipment is an Ethernet switch,
contact the manufacturer.
