We require someone experienced in a2billing to write a custom feature for us.
We are using Asterisk + a2billing for calling card and hence would like to add 'hotdial' function to a2billing. For this the customer there will several access numbers . The customer will be able to set predefined numbers against these number. Once the call these number and verified via their callerid the call will auto dial to the pre-set desired numbers
**Hot Dial** - If you have numbers that you call often and want to connect your calls even faster, you can use the Hot Dial option! This will associate an access number, with your PIN and a destination number. Also, you have to register the number you are calling from for Pinless Dialing (Register More Numbers section in your BananaCall online account). This way, when you use your phone to dial that particular access number your call will be connected. To call other numbers (besides the Hot Dial destination number) you can either dial a different access number, or dial the same access number form a different phone; the rest of the dialing process will be the standard.
