SERVICE PROVIDER VOIP NETWORK
Using a service provider VoIP network requires at least one VoIP-enabled phone system. 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.

To reach an outside party, the user dials the hunt group number associated with the service provider
profile, and then dials the phone number.
To reach a local extension, an outside party dials the VoIP number that was assigned to the system by
the service provider.
Before proceeding, ensure you have:
•
Connected the system at each location to a network (see page 2).
•
Configured local IP addresses (page 3), and public IP addresses if required.
•
Configured the router (page 6).
