Description (partial)


Phone default prompts and missed call details are not visible after a display message notification call via CiscoTSP.

Per CiscoTSP API documentation, phoneSetDisplay function call with "NULL Pointer" as lpsDisplay & "0" as dwSize should clear the custom posted phone display message, however with latest TNP devices it is not the case.

IP Devices 7941/61, 7970/71 etc...
