Activating and Configuring Queue Callback

When activated, Queue Callback (also known as virtual callback or virtual queueing) will dial your callers back if they hang up while waiting for 30 seconds or longer while in queue. Upon the call back, the agent will greet the caller by saying "Hello, I’m calling you back because it looks like we just missed your call" before the scripted greeting, so that callers are aware of who is calling them. You can choose to customize the callback greeting as well!

The Callback Feature works only if you are directly forwarded to service. If you are forwarding through a tracking system or masked number, we do not have the caller ID to call back the caller. In addition, callbacks may come through as Potential Spam, so your customers may not receive the callback if they have any Spam Blockers set up on their side. 

In this article we'll discuss:

When to activate queue callback

Queue callback is a great option to help keep those customers happy who don't have time to wait for a live agent. With queue callback activated:

  • Your callers will receive either a call back or an SMS message if they hang up after 30 seconds or longer while waiting for an agent. The call will drop into the queue and will be handled by the next available operator.
  • No additional fees are added to your monthly invoice - this is a free feature
  • The call is still processed by the first available receptionist
NOTE: Even if you have call recordings turned on, queue call backs are not recorded.

How to activate queue callback


Within SAS Flex, go to your User icon in the upper right-hand corner and click  Settings.


On the main Settings page, scroll down the Telephony section and select  Numbers.


Select the number where you want to add the Callback feature to.


Under Number Settings, choose  Callback. Then use the toggle to Activate Queue Callback

NOTE: If you currently have a driving question in your regular greeting, you'll want to add that same driving question to your customized callback greeting(s) as well.

Once activated, you'll have a few options to configure:


You can choose to have the system call back all callers, or only first time callers. If you choose First time callers only, note that the system doesn't reset. Meaning, if a customer calls 3 months ago and then calls again from the same caller ID, the system will not consider that customer to be a first time caller.

Enable time and date restrictions

Limit the hours or days of the week Queue Callback is active on this number. If this option is chosen, there are 2 secondary options to choose from; Range and By hour and day.


If this option is chosen, you'll need to select a timeframe in which you want the queue callback system to operate between.

By hour and day

If this option is chosen, you'll need to select the specific hours and days you want the queue callback system to operate. 


If callers don't answer the callback the first time, you can activate a Second Callback if no answer. To do this, scroll up to the Activate Callback section and toggle it on.

Then toggle on the Second callback if no answer option as shown below.

Sending an SMS message

If you'd prefer to send your mobile callers a Text instead of having us call them back, toggle on  Send an SMS Message to activate. Then, fill in the SMS text you want sent to callers. 

If the SMS feature is activated, it will override the queue callback. In other words, callers who hang up will not receive both a text and a callback. Note that if you have a Toll Free Number with SAS, SMS messages may not always go through.
