Constants

Disconnect Types

The value parameter of the telCADisconnectMsg message (page 5-17) indicates why a disconnect occurred. It contains one of the following constants.

enum {
   telCADNormal            = 1,
   telCADBusy              = 2,
   telCADNoResponse        = 3,
   telCADRejected          = 4,
   telCADNumberChanged     = 5,
   telCADInvalidDest       = 6,
   telCADFacilityRejected  = 7,
   telCADUnobtainableDest  = 9,
   telCADCongested         = 10,
   telCADIncompatibleDest  = 11,
   telCADTimeout           = 12,
   telCADUnknown           = 15
};

The telCADNormal, telCADBusy, and telCADCongested constants are meaningful for disconnects on a POTS line. The others are relevant only with certain PBX switches or ISDN lines. Consult your telephone tool documentation for specifics.
