Hi Harishkumar,

I have implemented a UDP/RTP based file transfer using mediastreamer2.
This is very non standard but as it uses RTP as a transport it works
transparently over a SIP network supporting audio and have pretty
good performance.

For this, I have implemented filters to define a decoder and an encoder
dedicated to file exchange. The RTP data contains formatted data to
echange file name and retreive block of files. The decoder acknowledges
the packet (DATA) received so that the encoder will resend all packet
loss.

If you want the standard way, it's much more work: you have to implement
MSRP.
