Call Origination Types

The intExt field of the call appearance structure contains one of the values listed in this section. The field provides information about where the call originated relative to the local switch or closed user group. For example, a call between two directory numbers on the same PBX system is an internal call.

You can use call origination types to limit the scope of operation of the TELCountCAs (page 4-57) and TELCALookup (page 4-57) functions. The following constants are defined:

enum {
   telInternalCall         = 0,
   telExternalCall         = 1,
   telUnknownCallOrigin    = 2,
   telAllCallOrigins       = 2
};
