Integrate voice and messaging APIs into applications To keep pace with the fast-moving application ecosystem, telecommunications carriers need to embrace API-based innovation. Using APIs as a means for enabling mobile and Web developers to leverage communication services in a language they understand significantly streamlines the development of new voice-enabled applications. However, it also raises significant security and management concerns. This joint solution from Layer 7 and Voxeo Labs, allows carriers to get new services to market faster and at a lower cost, in a secure, manageable way. It combines Layer 7’s SecureSpan API Gateway and API Portal with Voxeo’s Tropo (which enables developers to make and receive phone calls and text messages from any Web or mobile application) and Phono (which turns any Web browser into a multi-channel communications platform).

 Twitter connectivity. This means that new APIs can be quickly constructed
@layer7 and securely exposed through configuration and the visual policy editor
in Layer 7’s SecureSpan API Gateway.
Additionally, the Layer 7 API Portal provides a key interface for the
delivery of documentation, forums, an API explorer and other resources
that enable developers to: quickly discover and understand APIs; obtain
API keys and OAuth secrets; create applications and track usage.
Uniquely, the API Portal enables telcos to support internal, partner
and third‐party developers simultaneously, providing each group with
its own access privileges and community resources.
