Hang up a call

Ends one of your live calls. The call then ends the way any other call does once the disconnect is reported: an answered call as COMPLETED with call.completed, a call still ringing as NO_ANSWER, REJECTED or FAILED with call.failed. A call that has already ended answers 409, and so does a call with no phone leg, such as one between two app users.

Get a call GET

Retrieves one of your calls by id: the parties, the owning number, the current status with its failure reason, duration, price, recording availability, and a timeline of when the call entered each status.

Start or stop recording a call POST

Starts or stops recording one of your live calls. Use start to begin recording mid-call, or stop to end a recording, whether it was started here or by a connect answer with record set. A call that has already ended answers 409, and so does a call with no phone leg, such as one between two app users, which can't be recorded.
