Outbound call number

Outbound call number: the phone number used to make the outbound call. It can be selected from a dropdown list or set using a variable defined in the flow. The available phone numbers match those previously added to the Talkdesk account, under Admin > Numbers.

Destination number

Destination number variable: the phone number to call. A Studio variable containing the desired phone number can be selected here. This variable can be defined in the initial step of an API-triggered flow, which retrieves the phone number from the body of the API request.
Maximum ringing time: the maximum ringing time, in seconds, for the destination phone number. Values between 10 and 600 seconds are supported (15 seconds is the default).

Voicemail detection

Enable this option to detect whether the call is answered by an answering machine, then use the Voicemail detected exit to take action.

📘
Note
Enabling this option adds usage costs. Contact your Talkdesk representative for more information.

The detection mode can be set to either detect the voicemail and exit through the Voicemail detected exit, or detect the voicemail and wait for the tone to leave an audio message before exiting through the Voicemail detected exit.

📘
Note
When Answering Machine Detection (AMD) is enabled, the system takes approximately 4 seconds on average to analyze the call audio and determine whether the recipient is a human or a machine. To avoid silence during this period, an audio tone plays automatically, filling the gap until the system classifies the call and proceeds to the next step in the Studio flow.

Play audio message

The audio message the contact person hears in their voicemail can be configured as one of the following message types: "Text-to-Speech," "Audio File Upload," or "Other Sources."

Text to Speech

This option converts a typed message to audio and plays it to the caller. For more information on voice and language settings, see "Text-to-Speech Voice Settings" in this article.

Audio file upload

To play a pre-recorded custom audio file message, upload an audio file directly from a computer.

Other sources

This section supports entering a URL to retrieve an external file in MP3 or WAV format, or selecting a variable previously used in the call flow. Before saving the flow, click the Test audio button to confirm the file plays correctly.
