We want to begin with a new small VoIP business, something simply and easy. What we want is somenone that help us to setup some Elastix configs so customers can connect and have it's monthly billing. What we would like to setup is the billing interface and some callback - disa features, also monthly plans, but something very simply.
We already have a working elastix with A2billing and g729 protocol. Also we have two providers, one in Europe and another one in USA.
Maybe later we would need a kind of monthly maintenance and support.
