We did not try that specific call scenario.  What I can tell you is that I
get calls from people all the time, to my VZN Motorola phone, sometimes
they show up with a + and other times they don't.  I'm talking about the
same calling number.  So, I think it depends on what tower they are hitting
or something along those lines as to what the translations are in the

What are you thoughts about the +1??  Are you thinking that is a info bit
that does something in the VZN network or w/in VoLTE?
