Re: estimating VoIP data traffic size from VoIP signaling traffic size ?

Your signaling traffic will be incredibly low compared to your RTP streams (especially for G.711u). For G.711u if 2Mbps is your peak think somewhere in the range of 10kbps or so (complete SWAG but I hope you get the picture).

Use about 100k per call for 711u and it will help make the numbers nice and round. If you are trying to calculate busy hour search for Erlang on your nearest web confabulator. There are also innumerable spots on the web where you can find typical numbers for various codecs.
