SPA9000 IP PBX

The SPA9000 is an IP PBX that supports up to 16 phones. It also has a built-in
Analog Telephone Adapter (ATA) with two FXS ports for analog telephones, fax
devices, or an external music source for the music on-hold service. Devices
connected to the FXS ports are not included in the device count.
The SPA9000 has four line interfaces, which can be configured in any combination
for ITSP service, ISDN access, SPA400 PSTN access, or SPA400 voice mail
service. A different ITSP account can be configured on each line interface. If a
service provider supplies a group of sequential direct inward dial (DID) phone
numbers (such as 408-555-0100 through 555-0145) the SPA9000 can support all
of the assigned numbers on a single line interface.
