Hunt - Group - A group of telephone channels configured so that if<br />
the first is busy (engaged) the call goes to the next channel, if that<br />
channel is busy it goes to the next channel, etc. Hunt groups may<br />
hunt from the highest to the lowest, the lowest to the highest, or<br />
on some other arbitrary pattern. But the order of hunting will<br />
usually be fixed, beginning with one channel <strong>and</strong> working through<br />
("hunting") until an unused channel is found. The term may have<br />
originated back in the old manual switchboard days when the<br />
operator literally hunted for an unused jack to plug a cord into.<br />
This arrangement is very common in business scenarios where a<br />
single incoming number (the Listed Directory Number) is given to<br />
the public, but multiple incoming channels are supported. See<br />

Hybrid - 1. A device which converts from a two-wire signal such as<br />
POTS lines to a four-wire system (separate send <strong>and</strong> receive<br />
paths) such as used in the pro-audio world. While this task is<br />
theoretically quite simple, the fact the impedance of most phone<br />
lines varies widely across frequency complicates matters. 2.<br />
