Using DTMF signals, you can create an IVR menu that allows navigation through the bot's dialogue branches using the number keys from 0 to 9 and the symbols «*» and «#».
A DTMF signal is a tone signal sent when the user presses keys with numbers or symbols on their device while interacting with the bot.
This functionality is only applicable to voice bots, as sound signals are used for transitions between branches, so it is not recommended to use them in chats.
- Go to the Bot Scripts section in your personal account.
- Open the required script in the editor. If you don't have a script, create a new one.
- Set the Question block and enter text that matches your bot's logic.
- Set the Recognition field in the Question block to Normal (5 sec), so the user has time to press the desired button.
- Create several Information blocks according to the expected number of signals in the script.
- Draw arrows from the Question block to the created Information blocks, then click on the arrow.
- Specify the following parameters in the arrow:
- Output Data Type — DTMF Signal.
- Signal Type — Static.
- In the DTMF Signal field, specify a digit from 0 to 9 or the symbols «*» and «#».
- Save the script.
Thus, when the client presses one of the expected buttons during the call, the bot will transition to the corresponding branch of the script.
