In this case local outgoing calls would first be routed through the analog
lines and then onto
voip lines if busy. All outgoing LD and International calls go out on a voip
line(s).
One of the beautiful things about VoIP lines is that they can handle more than
one call at a time
(in my case 5). To obtain the same "erlangs" rating you would need 5 x
(equivalent)analog business lines,
an expensive proposition!
