The use of a metaphor — an implied comparison between two things of unlike nature — is a classic visual rhetoric tool. It has been put to use on the Virtual PBX site to help our users understand the underlying principle of what a Virtual PBX is, what the advantages of using Virtual PBX^® as a service provider is, and ultimately to enhance our users' online learning experience. Here are some points, which help explain the metaphor of the hummingbird.

Air travel. The symbol needed to be an object that travels through the air.

Fast. Like the hummingbird, setting up your Virtual PBX is fast.

Hovers. Like the hummingbird, an incoming telephone call will hover via the ACD queue until a receiver picks up.

Always in motion. Like a hummingbird that is constantly in motion to feed and pollinate plants and trees, the Virtual PBX is almost always on and working.

Light weight. Like the hummingbird, a Virtual PBX system is light, relieving the customer of heavy PBX equipment.

Friendly. Who doesn't like a hummingbird? Virtual PBX is a bright and friendly, providing consistent customer service and support.

Quiet. The Virtual PBX system has excellent sound quality.

Control. The hummingbird not only moves very fast but can control its movement incredibly well; Virtual PBX as a service puts a similar level of control in the users' hands when choosing their packages.
