Powerful Anti Fraud

Our Enterprise clients are able to take advantages of limits on their trunks to mitigate any fraudulent activity. We can set both a maximum cost per minute of a call as well as a maximum connection fee and we encourage all clients to take advantage of this.

Enterprise Trunk clients can also specify the dialling codes to be blocked or allowed and again, we encourage this. If you never call Afghanistan, don't have it in your allow list! This is a very powerful tool and allows thing like "All calls to UK except premium and also allow landline and mobile to France, Germany and Spain" etc.

This along with other measures that we do not disclose, allow our clients to sleep safely at night knowing that whatever happens, their liability is very limited.
