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 Connect, Dialpad 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:
Open the contact details
Select the contact’s name, or select the Skinny Bar
Select Edit (or Create if you’re creating a new contact)
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.
