Telephony projects and notes

Here are some of my notes and code relating to telephony. I am very interested in traditional phone networks, their design and their history. As well, I am very interested in Internet telephony signalling and protocol design.

What is here:

kphone is my VoIP application for KDE. It is currently maintained by wirlab and you can download modern versions over here.
Pictures of some really cool telephony test equipment I picked up dirt cheap. Makes some great furniture.
Some notes and code relating to SIP that I was involved with.
A simple SIP redirect server that I wrote.
krad is my 31337 tone dialer application for KDE.
