Simple Conferencing

Conferencing is common and useful voice application. A conference allows the audio of two or more callers to be bridged. Twilio's API lets you build simple conferences that just bridge audio or complex large moderated multiuser conference bridges.

Concepts

Twilio exposes the conferencing functionality through the Dial verb. Rather than dialing a phone number and talking to one other party, you can instead use the Conference noun and dial a conference room where you can speak to and hear all the other parties who Dialed the conference room with the same name.

Twilio implements the most common conference room functionality by default. By simply dialing a conference with the same name under the same Twilio account, multiple callers can now be bridged.

    • Twilio receives an incoming call from the second participant and also requests simple.xml
  • 4
