We are interested in building a VOIP website, using Asterisk & A2Billing platforms. Our users need to do following things
1. PC to PC Calls using Web Phone or any open source softphones (softphone customzied to our brand)
2. PC to Phone Calls using Webphone or any open source softphone (softphone customized to our brand)
3. Phone to Phone calls using IVR
4. Using A2Billling Customer interface, you need to customize the look and features according to our needs. One main feature we need is, as soon user registers after the e-mail activation, we need to give 5 minutes talk time for free,
I need a coder who is expert on Astrix/A2billing software and server setup as well as create and connection to a customer account maintenance website with e-commers (paypal/[url removed, login to view] etc).
