The project is to build a full virtual PBX system, both the back-end and front-end.
instead of writing all required features I would like you to see evoice . com
This project will be to create the same system.
Basically I would like clients to register and pay
Once they register they can transfer their existing number from us or buy a new number from us.
After that the client can configure extensions as they require by accessing their account on the website.
They can also specify where these extensions should ring.
Plus every feature provided by evoice . com
You would also need to advise what hardware and other equipment we would require.
