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

In this scenario, a 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 solution is to deploy LVS with the SPA9000 IP PBX, VoIP service, one SPA400 unit for voice
mail service, and one or two additional SPA400 units for PSTN access (four FXO ports per unit), and up
to 16 SPA9xx phones . Optionally, analog phones and fax machines can be added .
