ABOUT VOIP

VoIP-enabled TalkSwitch units route VoIP calls over the Internet or private IP network, and other calls over the traditional telephone network.

VoIP-enabled TalkSwitch units use the industry-standard Session Initiation Protocol (SIP) for VoIP calls. In this guide the term SIP is often used in place of VoIP.

About SIP servers

A VoIP network requires a SIP server to manage calls across the network. The SIP server contains registration information for all SIP devices in the network. When making a VoIP call, a device will contact the SIP server to get contact information for the destination. The device will then establish a connection with the destination. The SIP server is also involved with call termination.

All VoIP-enabled TalkSwitch units have built-in SIP servers to manage a TalkSwitch VoIP network, but you must designate only one TalkSwitch unit as the SIP server. TalkSwitch systems at other locations are configured as SIP clients.

Note: For VoIP calls made through a VoIP service provider, the service provider is the SIP server.

Selecting a location for the SIP server

Any VoIP-enabled TalkSwitch unit on the network can be designated as the SIP server.

To simplify network operation and reliability, we recommend that you choose a location that has a static, rather than a dynamic, public IP address. A static public IP address does not change, providing a consistent connection address for each location to communicate with the SIP server. See Setting the public IP address on page 6.
