This is OK, but the Pickup() application works with DUNDi too!? If I
do a call pickup, asterisk/dundi will lookup on every node for ringing
extensions?
In some tests this doesn't work for me. The Pickup() application only
look localy for ringing (and hint) extensions...
You make tests with this scenario? You can pickup calls on remote nodes?!

Thanks.
