We use SMSsync an open source SMS gateway for Android. Their API is fairly simple. You can see the documentation here: [login to view URL]
We would like you to create an exact duplicate of the example web service listed on that page but for Ruby on Rails.
We have an Android phone we can set up and you can using for testing. We can also provide a phone number you can send test SMS messages to.
We have already done this before and know it works. However, we have had problems with the Message Results API delivery report not being sent back. For our service it is very important that we get a delivery report and is the main reason for this project.
We DO NOT need the "instant reply as SMS to the user" feature in the example.
