Call Routing
CLIP Routing
Calling Line Identification Presentation (CLIP) routing is a supplementary GSM service used to show the
number of a caller.
Using CLIP routing, calls are accepted or rejected based on the calling number or a portion thereof. The
incoming call is analyzed for pattern matches to CLIP routing entries. If there is no match, then the “Reject
Calls Not Listed” checkbox is used to determine the processing of the call. If the box is checked, any non-
matching calls are rejected. Left unchecked, calls then are routed according to any Auto-call settings. If there
are no Auto Call settings present, then the incoming call is presented with a dial tone and the MVPGSM
waits for digits to be dialed by the incoming user.
