Hi, I see. I've been thinking about it and I've come to the conclusion that I'll try to implement the RTCP protocol by myself. What do you recommend me?, to use WP Classic or NG? I think that could be better for the community to make it in NG, but I'm scared about the fault of reliability, and the problems I would have to solve to make it work properly. Could somebody tell me how long could it take to implement the RTCP? If you think that this work could be very hard, please, tell me why, to consider it.
Thanks.

Port 10600 is reserved for RTP audio data by phapi. The "media-2.host.wengo.fr" machine is one of our RTP proxies.
