Keypress Collection (DTMF)

Enable your agent to collect keypresses from the caller's phone keypad. This is useful for:

  • Collecting account numbers or PINs
  • Multi-factor authentication
  • IVR-style menu navigation
  • Collecting numeric information that's easier to type than speak

Configuration​

Enable keypress collection: Turn this on to activate DTMF collection.

When enabled, you can configure:

Maximum Digits​

The maximum number of digits to collect.

  • Leave empty or set to 0 for no limit (digits are collected until timeout or # key is pressed)
  • Set a specific number (e.g., 4) to stop collection after that many digits

Example values:

  • 4 - For collecting a PIN
  • 10 - For collecting a phone number
  • 16 - For collecting a card number
  • 0 or empty - No limit (collect until timeout or #)

Range: 0-20 digits

Timeout (seconds)​

Number of seconds to wait after the last keypress before timing out and returning the collected digits.

The timeout resets after each keypress is captured, so it represents the pause duration between keypresses, not the total collection time.

Example values:

  • 5 - Standard timeout (recommended)
  • 10 - Longer timeout for uncertain inputs

Range: 1-60 seconds

Default: 5 seconds
