WiLine UCaaS WiLine UCaaS WiLine UCaaS

Use WiLine UCaaS to dial DTMF or pause during auto attendant interactions.

info

DTMF (Dual-tone Multi-frequency) signals are sent when you press numbers on your phone. Each number corresponds to a unique frequency pair used to interact with automated systems like auto attendants or IVR (Interactive Voice Response) systems. For example, pressing "1" sends one signal, while pressing "2" sends another, triggering the system to respond accordingly.

Dialing with DTMF​

To include DTMF tones, follow these steps:

  1. Enter the number on the dial pad.

  2. Before tapping (Call), add the required DTMF tones using the keyboard.

  3. Tap the dial field to type or show the keyboard (on iPhone).

WiLine UCaaS will dial the number and append the DTMF tones automatically.

DTMF Dialing Rules​

  • Start with at least one comma before the first DTMF number.
  • Each comma introduces a one-second pause.
tip

For a 3-second pause before sending "44", enter:

6045551212,,,44

tip

For a 6-second pause, followed by "1", "3", and "2" with two-second delays, enter:

6045551212,,,,,,1,,3,,2

warning

Save numbers with this format in your Contacts. On iPhone, tap the symbol key to switch between symbols and numbers. Use the Pause (,) for delays.

  1. Tap (Keypad).

  3. Tap Close Keypad (Close Keypad) to return to the call interface.
