    I would like to configure and customize A2Billing as follows:- Create a new signup page that has the look and feel of my current website- Change the customer user interface to have the look and feel of my current website- During registration / signup, allow new customers to chose a user name rather than use the one (card number or email address) assigned by a2billing. Allow customers to register a credit card so I can do auto recharge- Create a new recharge page in the customer interface for the use of all major credit cards (Amex, VISA, Mastercard, and Discover), and PayPal.It is very important that you have extensive experience with a2billing, and website development. It is also quite important that you have done something similar to this project.

Now my asterisk server again calls to that number (9884452152) and connects call 1 and call 2.On this way, i need now make an out going call to call from A to B , instead i achieve it via giving a missed call and get incoming call and connect A and B.Budget 50$

    On a2billing v 2.07. I am not quite sure whether it is called IN BOUND or OUT BOUND but all I want is my customers from their accounts address book on the website (which is written and synced with A2Billing) they will add 50 (that is the maximum length) destination numbers (e.g. 440834872638) as soon as they add the number a2billing will associate and route/map that particular number to a DID access number from its added 50 DID numbers so that customer never have to dial that particular that destination number again instead they will just that particular access number and this will have to happen for 50 numbers. At the moment A2Billing has a provision for 10 DIDs numbers which I heard can be mapped/routed but I need 50.Please if you have any experience in Asterisk/A2Billing and above all you know how to do this please reply otherwise not.Also, it has to be done within 4 working days.Regards
