Nimblevox is a cloud communications service with Hosted IVR, Automatic Speech Recognition, Text-to-Speech, Answering Machine Detection, Outbound Dialing, SMS Solution, Service Creation Tool, and Out of the box API's.
The SMS Receive API enables a callback to a URL you define in my.nimblevox.com. The URL is defined by configuring the SMS Receive URL for the phone number, and the callback is initiated from nimblevox. When a caller sends a text message to your nimblevox phone number, nimblebox sends the info to your url.
