Description of API

This function is responsible for Sending Call Waiting Notifications to the Remote Device. This function can only be performed by Audio Gateways which have Call Waiting Notification Enabled and have a valid Service Level Connection. This function accepts as its first input parameter the HFRE Port ID. The final parameter is the Phone Number required as one of the parameters within this response. This parameter is a pointer to a NULL terminated string (if specified) and must have a length less thanHFRE_PHONE_NUMBER_LENGTH_MAXIMUM. This function returns zero if successful or a negative return error code if there was an error.

Note: It is valid to either pass a NULL for the PhoneNumber parameter of a blank string to specify that there is no phone number present.
