We recently received $600 in call charges on one of our phone lines.  It happens to be the phone line that we are using for ADSL internet services.  Does anyone know if there are ways that a non-authorized person can make long-distance phone calls via the ADSL connection?

Thanks,

dauyeung,

I don't see any way for that to happen.  DSL uses a different part of the phone line than normal "voice" traffic.  DSL can cause interference but there would be no way for someone, even if they hacked into your computer, to then use the phone line.  To do that would take special, unique hardware in place of the DSL modem.

The cause of the charge will be somewhere else or might even be just a phone company error.

Let me know if you have any questions or need more information.

The only way i can see this happening, would be if the router is connected to both the DSL and voice side of the line, ususaly in a situation where either the router filters the PSTN line, OR, where the router would use a dialup backup when the DSL drops. it is possible that the router has been comprimised and has been used to dial out to premium rate numbers? Unlikely, but about all i can think of.

can your voice provider confirm itemised listing of the calls made?

Please explain the B grade!?  I'm glad we could help but the grade makes no sense, especially since you never commented.  Let us know if there was a mistake or you have some question.  It is nice to have a chance to earn the A or at least know why it wasn't.
