Frequently asked questions

Are Robocalls legal?

Yes. Robocalls are completely legal if you have the contact’s written consent. Political campaigns and nonprofits are the exception and don’t need to consent to make these calls.


SHAKEN/STIR is a new technology framework introduced to reduce illegal robocalls.
When adopted, carriers validate and attest your numbers to determine whether your calls should be labeled as ‘Caller Verified’ or ‘Potential Spam’.

When you sign up for CallHub, all your calls are SHAKEN/STIR compliant, at no extra cost.
Reach out to us here and we will take care of the rest.

How much does a robo call cost?

Since robocalls are automated calls without any agents, there are no agent connection costs involved as compared to call center campaigns. You only pay for the per dial cost and nothing else. Learn more about the pricing here.

How to set up a robo dialer?

Setting up a robo dialer campaign with CallHub is just a few simple steps. You start by uploading your audio message or adding it as text. Next, select your contact list to make calls to. Rent a number of your choice, use an existing one, or use our dynamic caller ID to make the calls. Once done, set the schedule based on appropriate TCPA complaint hours and you’re all set.

How to put a phone number on a robo dialer?

With CallHub, you have complete control over the caller ID that is displayed to the receiver. You can rent a number of your choice or use an existing one that you may have. Alternatively, you can also select our dynamic caller ID feature. It automatically rents out numbers to display a local caller ID based on the contact’s locations. Local numbers have higher answer rates making this feature quite handy.
