    Questions & Answers

    Sometimes I need to manually dial an extension after the call is answered. How do I dial digits in turboDial?

    The number keys on your computer keyboard can be used to create the digit tones and dial an extension. For example, if you call a number and want to reach extension ‘123’ then when the call is answered and you are prompted for the extension press the 1 key, then the 2 key, then the 3 key on your keyboard.

    Be sure your cursor is not planted in the Call Notes box in turboDial. When your cursor is in that box your keystrokes are recorded as typed notes rather than digit tone key presses.

    The phone I want to use as a Calling Device requires dialing an extension.

    You can enter an extension with the phone number you want to setup as a Calling Device. Include the extension after the phone number, and prefix the extension with a blank space and an ‘x’. For example: +13125551212 x1213.

    When you make a call using a Calling Device that has an extension Twilio starts by calling the phone number, then waits for answer, and then enters touch tones (DTMF) representing the extension. The Calling Device will then ring and when you answer the call will proceed to connect to the person you are calling.

    If you experience problems getting your Calling Device extension to ring when making calls then you should experiment with adding ‘pauses’ before the extension is dialed. You can add a pause by including a ‘w’ in the extension. Each ‘w’ equates to a 1/2 second pause. For example, an extension entered like this: +13125551212 xwwww1213 will result in 2 seconds of delay after the initial answer before the extension is dialed.

    The phone number I want to use as a Caller ID requires dialing an extension.

    You can enter an extension with the phone number you want to validate as a Caller ID. Include the extension after the phone number, and prefix the extension with a blank space and an ‘x’. For example: +13125551212 x1213.

    When you enter the number this way Twilio will call the phone number, wait for answer, and then enter touch tones (DTMF) representing the extension.

    The extension entered this way is used only to allow Twilio to reach you to verify ownership of the number. It does not become part of the Caller ID and it does not appear with the number in the Calling Device list.

    If you experience problems getting your phone extension to ring when validating a Caller ID then you should experiment with adding ‘pauses’ before the extension is dialed. You can add a pause by including a ‘w’ in the extension. Each ‘w’ equates to a 1/2 second pause. For example, an extension entered like this: +13125551212 xwwww1213 will result in 2 seconds of delay after the initial answer before the extension is dialed.
