SERVICE PROVIDER VOIP NETWORK

Using a service provider VoIP network requires at least one VoIP-enabled TalkSwitch unit. The service provider acts as the SIP server. The service provider assigns the VoIP numbers and VoIP configuration parameters.

For example, the following illustration shows a service provider VoIP network.

Figure 4: Service provider VoIP network

To reach an outside party, the user dials the line hunt group number associated with the service provider profile, and then dials the phone number. The TalkSwitch unit routes the call over the Internet to the service provider. If the outside party doesn’t use the same service provider, they are connected over the standard telephone network. If the outside party does use the same service provider, they are connected over the Internet.

To reach a local extension, an outside party dials the VoIP number that was assigned to the TalkSwitch system by the service provider. The call is routed through the telephone network to the service provider. The service provider routes the call over the Internet to the TalkSwitch system, which directs the call to the local extension.

Before proceeding, ensure you have:

•Connected the TalkSwitch system at each location to a network (see page 3).

•Configured local IP addresses (page 4), and public IP addresses if required.

•Configured the router (page 7).
