Deployment Scenarios
Getting Started
Deploying the LVS with ITSP Service Only
In this scenario, a customer has no legacy telephone numbers and does not require local voice
mail (either needs no voice mail at all or has voice mail hosted by the ITSP). The LVS is deployed
with the SPA9000 IP PBX, VoIP service, and four SPA9x2 series phones. Four phones are
connected at this time, but the LVS can be expanded to include 16 SPA9xx IP phones.
Optionally, analog phones or fax machines (not illustrated) can be connected to the two phone
ports on the SPA9000.
