Configuring Phone Lines and Calling Routing Behavior Configuring Line Interfaces on the SPA9000 4 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.
