UDP streaming instead of RTP streaming

[aikbeecisco]

Hi, I able to make RTP streaming by using xml services and  "RTPTx:......."  i get the streaming result and the protocol is RTP. But instead of using RTP as the streamming protocol, is it possible to making the transmit protocol as UDP without the rtp header?

Are you mean program or configure something inside the cisco ip phone?

[Gergely Szabo]

You can't configure the Cisco phone to do that.

Yes, you'll have to write a program that strips the RTP header. Meaning you intercept the packet, disassemble, take the payload, assemble a raw UDP packet, send.

Can the program implement inside the Cisco ip phone?

If you are a hacker, then yes. :-)

You can't !!!!

Come on. Everything is possible. Think positive.

I already gave him instructions:

1. intercept the packet,

2. disassemble packet,

3. take the payload,

4. create a shiny new UDP packet and send it.

For a moment I thought iptables "mangle" can do that, but I was wrong. Probably so probably libnetpcap. With jNetPcap, to be more precise.

NO, NO, NO, NO, NO !

The handsets are sealed, black boxes, as far as you are concerned. If they don't do what you want them to do, either buy other boxes, or write your own software running on your own systems to do the necessary stuff.
