Ah, and therein lies the rub.
Any sort of QoS frob that is implemented for VoIP (or any other traffic for that matter) _must_ be truly honored end-to-end, and at every intermediate hop in between, for it to be "guaranteed" -- otherwise when traffic that you may designate as "higher quality" is handed off to another administrative domain that does not honor your traffic classifications, all bets are off.
If you do not "own" the end-to-end network infrastructure, there is no way to guarantee any preferential handling of any particular subset of traffic.
So, set your Rate-Limiting of SIP traffic to 1 packet per second for the network that YOU control and then offer your VoIP subscribers a different QOS profile at a higher cost. Bingo, problem solved.
