In this blog we look at how to connect OpenTok Live Video sessions with traditional PSTN phone calls. We will demonstrate how to connect an OpenTok session to PSTN with an audio stream that connects through OpenTok SIP Interconnect to a Nexmo SIP-PSTN Gateway.
OpenTok SIP Interconnect is a general purpose SIP capability that can be used to connect to many different kinds of gateway or other SIP systems. TokBox is now part of Vonage, so in this blog we will use our own Nexmo programmable communications APIs to bridge the call.
As we continue to work towards enabling developers to reap the full potential of WebRTC, we wanted to demonstrate connecting a WebRTC audio stream with a PSTN user, using OpenTok SIP Interconnect and a third party SIP-PSTN Gateway.

It’s among the most frustrating of customer service experiences, not to mention inefficient and costly for operators.
