PSTN Access and Local Voice Mail

In this scenario, the customer requires a robust phone system but is not using VoIP
services. The SPA9000 Voice System is deployed with a SPA9000 IP PBX, one
SPA400 for PSTN access with four FXO ports, and another SPA400 for local voice
mail service. Up to 16 IP phones can be installed. Optionally, analog phones or fax
machines (not illustrated) can be connected to the two phone ports on the
SPA9000.
