I'm working on an application that will take in a media stream (between > 2 phones), do some transformations to the stream (i.e. make voices seem louder or softer) and then send it on to the conference bridge in the gateway for the individual streams to be mixed and then unicast back out.
The test environment that I have access to is using G.711 without any compression. Can someone tell me how I could go about intercepting the stream? I can get Administrator access to the network, so if there are options I need to set, that's more than possible.
I've very new to this stuff, and my prof wants results soon!! yikes!
The media stream between two phones consists of unicast UDP packets. I don't know if you will be able to intercept the rtp stream for that type of manipulation unless you act as an endpoint for the rtp stream and initiate the stream on another port to the other device. You will have to do this for each rtp stream (2 for duplex conversation). Check this site:
