[asterisk-dev] Asterisk modules in C++

[Deepesh D]

The AGI does some database lookups and based on the results sets some
dialplan variables. In the dialplan the call is routed to different
extensions based on the value of these variables. The database I use
is postgresql. The AGI uses libpq++ (postgresql's C++ interface) to
connect with database.
