I need the following things for my Voip Business.
1. A Voip server in Freeswitch where I can provide SIP accounts to my clients with some dedicated minutes for call. Also I want to provide multiple ports for single sip channels which means multiple calls can same at a same time for a single sip account and the total duration should not be greater than the minutes allocated to the sip account for all the ports/channels.
2. A billing and user management interface which I guess vBilling will do.
Please let me know was that possible and what is the charges.
