Olivier--

This is actually not a bad idea.Why single out just the Attended xfer? Why
would you treat
attended xfers differently than blind xfers? Just curious.

Also, calling just one macro for all features seems a bit restricted. Why
not allow the features.conf
to specify which macro/gosub to call, for each feature?  Dial is already
overloaded with options,
anything that could be offloaded would probably be desirable. Plus, calls
that were not initiated by
a dialplan "Dial()" invocation might not be able to provide that option.

Another question: what do you need this functionality to *do*? It could be
that there is an already
existing functionality that you could exploit to get the same results?
