Hi,

There was a discussion about NAT and relaying RTP about a half year ago, see http://mail.iptel.org/pipermail/serusers/2005-October/024562.html

Is the requirement that a client has to start sending RTP right after receiving the 200-OK defined by any RFC/draft/whatever? Links anyone?

As far as I know there is no such requirement and it is up to the client when does it start sending RTP.
