I need a system made which can accept MMS messages containing cameraphone photos from our gateway's API, check the phone number is on our database of subscribers, and then forward to a CS team/ticketing software. From this point, our agents will reply to the message/photo which needs to be sent back to the original phone number via SMS text message using the Gateway API.
In addition to the above requirements, I need the database for subscribers to be created, and a process whereby new subscribers are added to the database after having paid by Paypal (using Paypal notifications?). The database will also contain a 'credit' per subscriber per 30 days, which is reduced everytime they are sent a reply SMS message from our customer service agents. I will also require some kind of content managment end for the database where I can edit subscrib/ers details.
