I'd like to use the AAR feature to have incoming DID calls to remote site phones set for fwd'd bsy/na to vm, to use the pstn when the wan link is down or out of bw.
the site will have a pub 4.2, and unity 4.2 at central and a sub at remote. metroE link between sites.
Has anyone done this? If AAR reroutes call over pstn, what does caller hear when they reach unity? main greeting or subscribers greeting? I'd want them to reach suscriber greeting, same as when wan link is used.
