Call Forwarding Parameter Block

Your telephone tool passes a pointer to a call forwarding message parameter block to forward calls for a directory number to some other number. The call forwarding message parameter block is defined by the TELForwardPB data type.

struct TELForwardPB {
   StringPtr               forwardDN;
   StringPtr               forwardPartyName;
   StringPtr               forwardSubaddress;
   short                   forwardType;
   short                   numRings;
};
typedef struct TELForwardPB TELForwardPB;
