Directory Number States

The inUse parameter of the TELGetDNStatus function (page 3-22) returns a value that specifies a directory number state. The Telephone Manager defines these constants for directory number states:

enum {
   telDNNotUsed            = 0,
   telDNPOTSCall           = 1,
   telDNFaxCall            = 2,
   telDNDataCall           = 3,
   telDNAlerting           = 4,
   telDNUnknownState       = 5
};
