I already have an existing application that uses asterisk to connect calls and various other features. Each feature of the application can be manipulated via a PHP web service using custom API methods.
I want to add a new feature, to send a text message to a specified number. I need a custom API method on the existing PHP web service so that I can send a text messages on demand.
If this is something that you can do, please let me know how long and how much it would cost.
