5.3.2 Select which TalkSwitch to use as the SIP network server

A multi-location SIP 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 or receiving a VoIP call, a device will register with the SIP server, which will then route the call to the appropriate destination.

TalkSwitch units have a built-in SIP server to manage a VoIP network. Though every networked TalkSwitch unit has the capability, you must designate only one TalkSwitch unit in a network as the SIP server.

For VoIP calls made through a VoIP service provider, the service provider will act as the SIP Server.

5.3.2.1 Which location and unit should be the SIP server?

Any TalkSwitch unit on the network can be designed to be 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.
