It is not supported by rtpproxy. But you could run all that traffic inside a high-compression IP-in-IP UDP tunnel, though there would be an overhead penalty there too.

Doesn't seem to me like this stuff really saves a lot of bandwidth, especially in a way that has meaningful network oversubscription returns. You might be better off just using a low-bandwidth codec than worrying about all this.

Hello,

We are looking into bandwidth conservation by implementing RTP/UDP/ IP header compression.

Has anybody implemented ROHC or another header compression scheme in combination with kamailio + rtpproxy ? Could you please point us to online documentation or other useful resources ?

Thanks and Regards,
Vikram.
