I basically need the following:
It must do integration/communicate between A2billing (on freepbx) and WHMCS. It must be a set of a2billing server automation modules and an addon for WHMCS that allows for the creation, termination, suspension and un-suspension of reseller, client and extension accounts on a2billing servers.
It also allows automated 'pre-paid airtime' / 'pre-paid calling time' allocation AND 'post-paid limit' increases to reseller, client or extension accounts on my a2billing server.
It must be a VoIP related server provisioning & automation product for WHMCS, and must provides an easy way of adding completely automated VoIP products to my current product portfolio through my WHMCS online store.
It must be an extremely feature-rich, flexible and stable VoIP platform that allows me to sell SIP based services such as individual SIP accounts, SIP trunk accounts, hosted PBX's, traditional calling cards, hosted Interactive Voice Response (IVR) services, virtual conference services and virtual call centre services.
It must do the same as VoIP AutoPilot VN for WHMCS - Rack31 (VoipNow)
