Retell Voice Firewall is designed stop unsolicited calls and reduce excessive bills through telephone system fraud, enhancing your telephone system security
Retell Voice Firewall recognises unauthorised numbers and prevents hackers connecting to the main system, therefore nulling any opportunity the hacker has to penetrate the system. You can further configure the system to your own requirements and preferences. For example, you can determine which numbers should be blocked during office hours and out of office hours, so you won’t lose potential business from new callers that the system doesn’t recognise. Furthermore, Voice Firewall creates an event log showing blocked calls and numbers. You can also limit the number of simultaneous incoming and outgoing calls out of hours further enhancing your telephone system security.
Retell Voice Firewall has been specifically designed to be simple to install, and to work with any telephone system. Voice Firewall connects easily between the phone system and the network termination point, with no need to turn off trunk to trunk dialling if your system is using this functionality. What’s more, Voice Firewall does not limit ANY of the existing functionality of your telephone system. An overview of the benefits are shown to the right hand side.
