We have a running installation of Asterisk and we want to develop a prepaid billing(registration) platform for our customers.
Billing & self service CRM Module features:
User/number registration in(from) our existing mysql database connected to Asterisk(for example: we have 1000 free numbers in the database as a registered user gets(on email) first free + pregenerated password from the same table - "sip_buddies" and so on)
User should be able to top-up account using IVR or our Website payment gateway.
User shoul be able to see their own CDR records.
All this packaged in user-friendly web platform with landing page and standart About/Rates/etc sections.
