Hi,

I am planning to develop a small application that displays the details
of the active calls in a VoIP network and its QoS values. Obviously,
the details will be got from the RTCP packets.

I am looking for a sniffer that decodes the RTCP packets from the
network and provide a human understandable information of the RTCP
header. As this is an individual project/product, I am looking for a
free/very cheap solution. A platform neutral solution would be an plus.
Any tools that you have come across?

Thanks for your help.

With Regards,
Stephen Regan.

Take a look on Ethereal project. At least it is very good for debug
purposes (not only RTCP but large family of protocols). I am not
familiar with license of this product and can't say what exactly you can
get from it as a 'brick' for your development.

As for me i use it for a long time as good offline visualization tool
(in conjunction with tcpdump) and i'm not trying its capture facility.
