You can do this by setting the outgoing call cost per minute this feature was designed to help agents who may not know the per-minute calling costs for all countries. As an admin, you can manage monthly billing by restricting callers from calling countries that exceed your set price limit.
You can set the price limit for outgoing calls using the steps below:
Step 1: Log in to your CallHippo Dashboard https://web.callhippo.com/dashboard
Step 2: Click on "Setting" in the left-hand side panel.
Step 3: Under “Setting” click on "Price Cap"
Step 4: You can enter between $0.01 to $100 and click on the floppy sign to save the price. Calls costing more than the specified per-minute call rates will not be processed.
Step 5: If you call outside your price cap, you will get a notification.
Note: The limit is only for outgoing calls.
