After adding in a "wait(3)" to the extensions.conf, at s,2, I still get 
no audo be passed to me. However, I noticed that each time I place a 
call, asterisk thinks that two calls are happening. Here's the log 
output of what happens (all with no audio):

Notice that "Starting simple switch on 'Zap/2-1'" happens almost 
immediatly after it starts on Zap/1-1. Caling in multiple times results 
in nearly identical output, with the only difference being which line 
Zap/2-1 starts at.
