Phone line monitoring


Recommended Posts

Anyone got any ideas..?

Hey Dave,

thanks for the good site.

What i am looking for is a way to monitors phone lines for any intrusion, tampering , tapping or surveilence. There are several lines in the building, and i wonder if is best to monitor the risers.

Any suggestions would be greatly appreciated.

Thanks,

Its very difficult to monitor for this or to prove it is actually happening.

Without going into the technical details of how to do it (open forum & all of that stuff), its possible to listen in on a line without physically making a connection to the equipment or cables anywhere between the Exchange & clients property regardless of the service provider.

Pete is right, but from experience, certain service providers are not too helpful (would never admit to it happening to them) and due to the Data Protection Act, would not tell you who was doing it anyway and would pass the info onto the Police if they were asked / forced to monitor your lines.

VoIP

Voice of IP, it is new technology - but if you really wanted to secure your voice comms. Utilise your local LAN network and the public internet, I am not 100% sure but a minimum connection speed would be an ISDN line to the Internet - The second problem not sure if you can keep your original numbers but you never know?

Using the digital comms will make it easier to encrypt

Vigor routers from Draytek offer voip, which can be inside a vpn, therefore i suggest its pretty secure, especially if you use redcare on the same adsl/shdsl line.

Tip, buy your telecoms services through siemens, they guarantee 4 hr response and if your line(s) are down for more than 10 hours in a month they dont charge you!
