Quoting JTD <jtd(a)mtnl.net.in>in>:
That is right. But kind of doubles the cost - 2 PBXs,
two phones per
desk, etc. and halves the utility.
Actually this works great when a company has multiple offices and has
too many inter-office phone activity (cutting those calls to zero, and
thats perfectly LEGAL)
Also providing IP phones only on top executives desk who needs to be in
touch with branch offices India wide.
