Aculab Cloud enables users to create scalable voice, SMS and fax applications. It is a Communications platform-as-a-service (CPaaS), presenting high level APIs (Python, PHP, Java, Ruby and .NET) making it quick and easy to write a range of applications.
The developer account is free and once you wish to run your application you simply pay per minute for the runtime of the application. In addition you can purchase a range of international inbound numbers, and make use of the international carrier relationships in place to make outbound calls or send SMS messages.
Users can write applications to manage interactions and call logic including transfer calls, play messages, add calls together in a conference and more. The RESTful API provides programmatic access to the Cloud Filestore, whereby a suitable program may download, upload, delete or rename media files.
Multi-language text-to-speech (TTS) and automatic speech recognition (ASR) are included at no extra charge.
