[asterisk-users] CallingCard Applications

[Michael]

I want to build my own calling card system on Asterisk.

I looked at this page - 
http://www.voipinfo.org/wiki/view/CallingCard+Applications

and it has listed some applications that I thought could help speed up the 
development process though the link down the bottom doesn't work.

Does anyone know of any AGI etc applications to build a Calling Card system on 
Asterisk?
