One of our customers had been located on the first floor of their building for quite some time.  They had grown, and had
leased additional space on the second floor to expand into.  The problem that developed was that physically, there was
no way to run cable from the first floor to the second.  Our solution was to give them two wireless access points, one on
each floor.  The access point in the new, second floor suite went to a network switch, then to the Allworx phones. 
Everything worked great, and together with the customer we worked out a solution that with an Allworx, is easy.
