We have a release 8 Definity PBX (this PBX does not have any call center features). We also use an external monitoring system to record calls on certain extension 24 x 7. Currently we install these beep-tone boxes to the handset to beep every 10 seconds alerting the caller that their call is being monitored. We have to do this by law. Is there anything inside of our system that would give off an audible beep based on the extension the call is going through? Would this be in the station form or COR? Any help or suggestions would be greatly appreciated.
