Post-Dial DTMF Strings

Post-dial DTMF strings let you append PINs or other ID numbers to a particular contact number, using the comma (',') character to represent 2-second pauses in sequence.

They’re particularly valuable if you have standard conference bridges you repeatedly call into, wherein you need to enter a PIN or ID number to access the bridge.

Let’s dive into the details.

Who can use this

Dialpad ConnectDialpad Sell, and Dialpad Support customers can use post-dial DTMF strings.

Add Post-Dial DTMF string for a contact

Post-Dial DTMF Strings can be added when editing or creating a new contact.

To add a Post-Dial DTMF String:

From the Dialpad conversation:

  1. Open the contact details

    1. Select the contact’s name, or select the Skinny Bar

  2. Select Edit (or Create if you’re creating a new contact)

  3. In the phone number field, enter a comma (,) to represent a 2-second gap in sequence after the number itself

Multiple gaps can be added to ensure you don’t have to enter multiple PINs.

For example, if you frequently dial into a conference bridge at (555) 555-5555 and need to enter a PIN of '1234' six seconds after connecting, followed by '5678' eight seconds later, you would enter the contact number as (555) 555-5555,,,1234,,,,5678.

This way, you only need to select 'Call' to join the conference bridge, and you won’t have to manually enter both PINs each time.
