3This is an example of how to use the B2ABSession - a kind of
4b2bua where SEMS stays in the media path, or media relay.
5
6Because SEMS stays in the path, its possible to react e.g.
7on DTMF while in the call - and the jukecall example does
8just this:
9First it plays a welcome message to the caller, then it
10connects to the originally dialled number stripped by the
11first three digits. When the two parties are connected,
12the first one can play some files into the call by pressing
13the keys on the phone.
