Jukecall

This is an example of how to use the B2ABSession - a kind of 
b2bua where SEMS stays in the media path, or media relay. 

Because SEMS stays in the path, its possible to react e.g. 
on DTMF while in the call - and the jukecall example does 
just this:
First it plays a welcome message to the caller, then it 
connects to the originally dialled number stripped by the
first three digits. When the two parties are connected, 
the first one can play some files into the call by pressing
the keys on the phone.

for example:

123@example.org    SEMS jukecall       456@example.org
