API Connections to SMS & Voice Gateway

We have an SMS and Missed Call Alerts Account where by we have the api for the same. We need a basic application, where there are the following operations held. When someone calls, the number is collected into a database. and then also a unique number gets generated for every unique number collected . 1. Person calls , gets unique number as sms on their cell. 2. After he receives.. he can go back to the store and avail a discount by manually showing the unique code message over the desk. 3. At this point, the staff logs into the admin, sets the unique number as used. 4. If the same number calls back, he gets a message saying, he has availed the offer already. 5. If the same number calls back, but if he has not availed, then the message that goes is again with the same old unique number generated under his mobile number. Basic idea on the Voice Call API Data How To use Missed Call Alert Simply give a Call on your Incoming Number Forwarding URL [Optional] In case you want to store the data ie. the Missed Call Alert from number, you can do that by using our variable name mcafrom [Mandatory] In this Variable you will Receive Incoming Number Value cdt [Optional] In this Variable you will Receive Call Date, Time cdt Format: dd-mm-yyyy Hour:Min:Sec eg. 05-08-2012 20:05:08 var1 [Optional] {Will be available on Request. } This Variable will be your Missed Call Number Example API: http://YourDomainName/[login to view URL] This is 1st phase of a application required. And this is urgent. Rest assured of all other phases to the bid winner. Only serious people may bid. Regards
