Desktop Passthrough (DTPT) is the technology that allows the Windows® phone to talk to the desktop network while ActiveSync is running.
DTPT is implemented using a socket level proxy technology. A proxy server runs on the desktop as part of ActiveSync, while a transport proxy client runs on the Windows phone. This transport client is the DTPT LSP.
The following is the sequence of winsock calls made by the DTPT LSP:
def WSPConnect(addr):
if is_dtpt_enabled():
connect_to_dtpt_server()
dtpt_server_connect_to(addr)
else:
let_connect_call_passthrough_to(addr)
