Unfortunately it does not work.
Neither works under SP1 Service X_InboundCallRoute: {ph1,ph2},{pp(500111111)} nor under CallForwardUnconditionalNumber field: pp(500111111) or pp(ob500111111)

GV answers the call, prompts for the caller name, rings 4 time but incoming call is not forwarded to my ObI202 in Italy.
There is something wrong. Maybe I'm tired now, after a day of work and it should be better for me to go to bed because even the :aa for "2 Make a new call" doesn't work. Is it that way (aa prompts) to make calls to USA numbers via GV from Italy you spoke about, or do you have a smarter way to place calls from Italy via GV registere on my NY City device? With some simple configuration changes other than aa prompt?
Thank you azrobert for your help
