This technology has been around for a few years but only now is the small business starting to take advantage of the benefits.  There are different ways to leverage VOIP in your business;  1) install a single VOIP phone at home on a Comcast connection to allow key employees to “telecommute”,  2)  connect a Seattle office with a Portland office over the internet eliminating interoffice long distance, enabling 4 digit dialing, and sharing resources from one site such as “networked voicemail”,  3) enable a mobile sales person to always be on the move yet outbound calls from a “soft phone” installed on a laptop no matter where the rep is in the world.  ITN is currently working with an ITN AVAYA IP Office phone system client who is expanding into an adjacent building next door.  Rather than trench the parking lot and install a 900’ fiber/copper backbone, ITN can use their robust internet connections at each site, QOS rated firewalls, and two separate AVAYA IP Office systems tied together over VOIP!
