Absolutely right. Though in India we have been charging the regular call center model for our cloud call center, http://cloudagent.in, we knew the model will not continue for long, especially in the US. So for our US product getkookoo.com we did away with the per agent pricing. We went with a zero agent rental and fixed monthly cost model with free minutes included[1].
