Deployment Scenarios

Deploying the LVS with ITSP Service, PSTN Access and Local Voice Mail

In this scenario, the customer wants to use ITSP service for reduced long distance fees but
needs to support legacy local telephone numbers (for example, to receive calls over the
original legacy telephone number, or to route local telephone calls). This customer also prefers
local voice mail service. The LVS is deployed with the SPA9000 IP PBX, VoIP service, one SPA400
unit for voice mail service, another SPA400 units for PSTN access with four FXO ports, and up to
16 SPA900 series phones. Optionally, analog phones or fax machines (not illustrated) can be
connected to the two phone ports on the SPA9000.
