I am in this business and I think the general execution seems reasonable if it works as advertised. However you need to secure at least one big partner or a few smaller ones. May be Plivo themselves, they should be interested to help out promoting a good product based on their platform. You will need funding to develop the whole thing into a unique appealing product with some differentiators - some harder technical features, better artwork/UX if you will.
My advice is don't put more cash into it for now, go talk to Plivo, talk to a few call center companies see if anybody wants to be a partner on reasonable terms. In the mean time look for a team and funding. Not freelancers, a few guys part time, working for shares is better for VC.
Thank you - this comment is buried but it's excellent advice and I will be taking it seriously. Currently chatting with one of the co-founders of Plivo so watch this space :)
