Send DTMF request

digits

string

required

DTMF digits to send. Valid digits are 0-9, A-D, *, and #. Pauses can be added using w (0.5s) and W (1s).

Example:

"1www2WABCDw9"

duration_millis

integer<int32>

default:250

Specifies for how many milliseconds each digit will be played in the audio stream. Ranges from 100 to 500ms

Example:

500

client_state

string

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

Example:

"aGF2ZSBhIG5pY2UgZGF5ID1d"

command_id

string

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

Example:

"891510ac-f3e4-11e8-af5b-de00688a4901"

Response

Successful response upon making a call control command.
