Do Not Call

Stop calls to numbers on your do-not-call list.

Do Not Call checks every outbound call against your own lists and drops the call when the number matches. It is designed to help you comply with your do-not-call policies.

  • Email alerts for selected extensions
How it decides

Block the numbers on your list, or allow only those numbers.

Do Not Call is a Windows service that watches every outbound call. You choose how it uses your lists, and which extensions the rules apply to.

  • Block ListOutbound calls to any number on your lists are dropped.
  • White ListOnly numbers on your lists can be called. Calls to every other number are blocked.
  • Lists from CSV filesImport named lists from comma or tab separated files, and match the columns to the Name and Phone fields.

You can also exclude extensions from the rules, and set how many digits to compare so numbers match with or without a country code.

Settings: choose Block List or White List, how many digits to match, and when expired numbers are removed.

Why it matters

A list only protects you when every call is checked against it.

A list people have to remember
With Do Not Call
A do-not-call spreadsheet each agent has to check before dialing
Every outbound call is checked against your lists automatically
A listed number gets dialed anyway
The call is dropped when the number matches
Nobody hears about it until later
Extensions you select trigger an email when they dial a listed number
No record of the attempts
The report shows the extension, agent, dialed number and time of each attempt
Old entries stay on the list forever
Numbers with an expiry date are removed automatically at the time you set
Import

Bring in your lists from a CSV file.

Managers import contacts from a CSV file into one central list, name each list, and map the file's columns to the phone number, registration date, expiry date and description.

  • Comma or tab separated files
  • Export your lists back to a file at any time
  • Restart the Do Not Call service after an import so the new numbers apply
Exclusions

Let the right extensions through.

Some extensions may need to call numbers that are on the list. Tick them in the Global Exclusion List and they can bypass the Do Not Call restrictions.

  • In Block List mode, you can also allow chosen extensions to call one specific listed number
Where it helps

Wherever your team dials out, the list is checked first.

Outbound sales teams

Load your internal do-not-call list, and calls to those numbers are dropped automatically.

Call centers

When a customer asks not to be called, add the number to your list with your next import, and future calls to it are dropped.

Teams that call approved numbers only

Switch to White List mode so agents can only reach the numbers on your lists.

Managers who need a record

Review every blocked attempt by extension, agent, number and time, and export the report.

Do Not Call is included in the VoIPTools Subscription.
