National calls should be something like +1NPANXXXXXX. An international call would never begin with +1 unless you start getting into the NANPA “International” destinations such as Canada and the Caribbean that share the 1 CC. For example, if I send an international call to another major SIP trunking vendor, the URI would be +442074999000 (this is the US Embassy in London).<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I have never personally worked with Verizon’s SIP trunks, but I would expect them to have a reasonably sophisticated rating engine that knows all of those details.
