Trying to set up daily limits

Hello,

I am trying to configure ASTPP to be a sort of proxy for international calls on our system. Our clients will not have access to this server and there will be no payments that passthrough the system.

The goal is to set a limit of 50$ daily and to ensure that the limit is not passed and resets everyday. We will have upwards of 200 PBXs trunked to ASTPP for international calls. All of which are hosted and managed internally.

Any recommendations on what kind of setup can be used?

Thank you,

Matt
