Unfortunately, Not possible right now without human intervention!
However, if there are any scheduled calls in the campaign you will be able to pause the campaign only for the scheduled ones.
For example, if you have run the campaign to 100 numbers and 70 are still in a scheduled state, you will have an option to pause the campaign as shown below.
However, if the count of the scheduled numbers is 0, you will not be able to pause the campaign.
In case you would want to stop the campaign if it is very necessary, we would recommend that you delete the campaign. Please note that once you delete the campaign, the details of that campaign will not be available on the dashboard.
