As shown, the SPA9000 provides four logical line interfaces, referred to as Line 1,
2, 3, and 4. Each line can be configured with the same or a different ITSP. Each
SPA400 also occupies one line interface. The SPA9000 has five internal clients
that register implicitly with the internal SIP proxy:
•
FXS1 (fxs1)
•
FXS2 (fxs2)
•
Call Park (callpark)
•
Auto-Attendant (aa)
•
Internal Music Server (imusic)
FXS1 and FXS2 correspond to the two physical FXS ports. The FXS ports can only
register with the local SIP proxy. The Call Park is used to maintain calls that are
parked, and AA is a scriptable auto-attendant application.
