to get more profitable whatconverts support is a must for call tracking. It brings the cost down and it a far superior product. example with call rail if i do 10 clients its going to cost me $1500 a month, while only cost me around $250-$400 a month with whatconverts and the reporting is way way way better. It hard to be profitable with callrail. sort of a show stopper for me with Dashclicks. If you have not tried whatconverts give it a go and see how it blows cail rail out the water.
