Configuring Line Interfaces on the SPA9000
You can configure the following types of services on the SPA9000 line interfaces:
• ITSP service: Up to 16 DID numbers can be supported on each line interface. You can
configure different ITSP accounts on different line interfaces.
• PSTN service: You can configure a line interface to register the SPA9000 with a SPA400
to support PSTN lines.
• SPA400 voice mail service: You can configure a line interface to register the SPA9000
with a SPA400 to support voice mail server. This SPA400 should have no more than two
PSTN lines connected. If more than two PSTN lines and voice mail are required, you
should reserve one SPA400 exclusively for voice mail. Exceeding these guidelines will
affect the quality of voice mail playback and command recognition.
• ISDN services: You can configure a line interface to register the SPA9000 with a
Mediatrix® 4400 ISDN BRI Digital gateway. For more information, refer to the SPA9000/
Mediatrix® 440X ISDN Gateway Configuration Guide, available at www.linksys-itsp.com
(for Europe, Middle East and Africa Service Providers) and www.linksys-voip.eu (for
Europe, Middle East and Africa Value Added Resellers).
