Books are one of the best resources, the Wiki is not *too* bad when it 
comes to general telecom stuff.  You can also build prototype systems.

No, Asterisk did not suddenly unleash the gates of knowledge in telecom. 
  All that information was available before Asterisk.  What was not 
available was info on the specific inner workings of traditional PBXs.

Asterisk and Digium did reduce the hardware cost of building a PBX.

Traidional telecom is actually fairly simple if you compare it with IP 
PSTN/IP PBXs.  With an IP PBX like Asterisk you need to understand 
telecom, IP networking (including routing, NAT, ports), Linux, as well 
as Asterisk itself.
