I need to have a VoIP running on 2 sites, below is the diagram:
Site 1 Site 2
[PBX]---[Router1]---------Leased line---------[Router2]---[CO]
In Site 1, is it enough to test the configuration of one call leg from PBX to Router1 even without the leased line yet? If I get a tone from the Router 1, does that ensures me that my Site1 is working? Please pardon my basic question.
