Nexmo VoiceXML allows developers to integrate their applications with the Nexmo Voice services, enabling their users to call, text to speech through Nexmo directly from their applications. Nexmo provides customers a way to communicate with one another domestically and internationally.
Vonage today announced that it is acquiring communications platform-as-a-service provider Nexmo in a cash and stock deal valued at $230 million. Nexmo counts some 350 customers and over 100,000 registered developers, and says that it is processing 5 billion API calls every year.
