Let's work to set up secure VOIP, but
don't let anyone kid you about the golden days when telephones were secure!
(for extra points, why's the hacker mag called 2600?)

Hope this isn't too far OT, but its relevant to us. From isn.attrition.org
As others have said, 2600Hz is a widely used signalling frequency.
Before ISDN and SS7 a large amount of telephony signalling consisted
basically of beeping at 2600Hz in America, or 2280Hz in many other
countries. If the filters in the network were inadequate (they usually
were) you could send strong signalling tones yourself, get through the
filters, and have your tone detected by the far end.
