This function parks a call. Only park mode lineParkMode_Directed is supported. The park address can be any alphanumeric string. However, only numeric digits can be entered from a telephone, to restrict your park addresses to numeric strings. The four default park addresses that display in IP Office applications are 1, 2, 3 and 4. Use these numbers to unpark parked calls using the default configuration.
