Here is the answer and it is done on the carrier side. Note: this is for Bell Canada/Mobility enter *94 then the number of rings you want, say 4, you would enter *944 press send then wait for a rather long dialtone of 4-5 seconds... thats it you are done. Just a guess but I think *94 would work for most of the B side carriers like SBC and Verizon.
