I have a web based reminder app located here [login to view URL]
It currently uses [login to view URL] to send voice and text messages. I would like to use a new provider [login to view URL]
Your task will be to mod ify the custom script to send messages via tropo and use twill as a backup provider if the message fails. The Apis of both services look fairly similar so this should be a standard switch.
You'll need to have experience working in php, mysql, and with develop Apis
I have very extensive knowledge of sms systems. I have develop a couple of sms sites using http,smpp api. I have also developed my own api. This project is just to develop a good relationship with a potential client.
