There are a number of other reasons you want a remote phone server at
that other location:
*911 or name-the-emergency-service of your country
*how do you call the other employees at the branch office when the WAN
link is down?
*this multiplies your options for future growth / expansion /
flexibility / when you decide that you would rather have a dedicated
telco link joining the offices.
