Call Commands

Bridge calls

Bridge two call control calls.

Expected Webhooks:

  • call.bridged for Leg A
  • call.bridged for Leg B
post/calls/{call_control_id}/actions/bridge

Path parameters

call_control_idstring required

Unique identifier and token for controlling the call

Request body

call_control_idstring required

The Call Control ID of the call you want to bridge with, can't be used together with queue parameter or video_room_id parameter.

client_statestring

Use this field to add state to every subsequent webhook. It must be a valid Base-64 encoded string.

command_idstring

Use this field to avoid duplicate commands. Telnyx will ignore any command with the same command_id for the same call_control_id.

hold_after_unbridgeboolean

Specifies behavior after the bridge ends. If set to true, the current leg will be put on hold after unbridge instead of being hung up.

mute_dtmf'none' | 'both' | 'self' | 'opposite'

When enabled, DTMF tones are not passed to the call participant. The webhooks containing the DTMF information will be sent.

park_after_unbridgestring

Specifies behavior after the bridge ends (i.e. the opposite leg either hangs up or is transferred). If supplied with the value self, the current leg will be parked after unbridge. If not set, the default behavior is to hang up the leg.

play_ringtoneboolean

Specifies whether to play a ringtone if the call you want to bridge with has not yet been answered.

prevent_double_bridgeboolean

When set to true, it prevents bridging if the target call is already bridged to another call. Disabled by default.

queuestring

The name of the queue you want to bridge with, can't be used together with call_control_id parameter or video_room_id parameter. Bridging with a queue means bridging with the first call in the queue. The call will always be removed from the queue regardless of whether bridging succeeds. Returns an error when the queue is empty.

record'record-from-answer'

Start recording automatically after an event. Disabled by default.

record_channels'single' | 'dual'

Defines which channel should be recorded ('single' or 'dual') when record is specified.

record_custom_file_namestring

The custom recording file name to be used instead of the default call_leg_id. Telnyx will still add a Unix timestamp suffix.

record_format'wav' | 'mp3'

Defines the format of the recording ('wav' or 'mp3') when record is specified.

record_max_lengthinteger

Defines the maximum length for the recording in seconds when record is specified. The minimum value is 0. The maximum value is 43200. The default value is 0 (infinite).

record_timeout_secsinteger

The number of seconds that Telnyx will wait for the recording to be stopped if silence is detected when record is specified. The timer only starts when the speech is detected. Please note that call transcription is used to detect silence and the related charge will be applied. The minimum value is 0. The default value is 0 (infinite).

record_track'both' | 'inbound' | 'outbound'

The audio track to be recorded. Can be either both, inbound or outbound. If only single track is specified (inbound, outbound), channels configuration is ignored and it will be recorded as mono (single channel).

record_trim'trim-silence'

When set to trim-silence, silence will be removed from the beginning and end of the recording.

ringtone'at' | 'au' | 'be' | 'bg' | 'br' | 'ch' | 'cl' | 'cn' | 'cz' | 'de' | 'dk' | 'ee' | 'es' | 'fi' | 'fr' | 'gr' | 'hu' | 'il' | 'in' | 'it' | 'jp' | 'lt' | 'mx' | 'my' | 'nl' | 'no' | 'nz' | 'ph' | 'pl' | 'pt' | 'ru' | 'se' | 'sg' | 'th' | 'tw' | 'uk' | 'us-old' | 'us' | 've' | 'za'

Specifies which country ringtone to play when play_ringtone is set to true. If not set, the US ringtone will be played.

video_room_contextstring

The additional parameter that will be passed to the video conference. It is a text field and the user can decide how to use it. For example, you can set the participant name or pass JSON text. It can be used only with video_room_id parameter.

video_room_idstring uuid

The ID of the video room you want to bridge with, can't be used together with call_control_id parameter or queue parameter.
