Chapter 6. "Let me in!"—Inbound Call Routing
"Would you tell me, please, which way I ought to go from here?" asked Alice.
"That depends a good deal on where you want to get to," said the Cat.
"I don't much care where —" said Alice.
"Then it doesn't matter which way you go," said the Cat.
"—so long as I get somewhere,'"Alice added as an explanation. —Lewis Carroll, Alice's Adventures in Wonderland.
When a call is intercepted by a PBX system, its handling is very much like Alice's trips into wonderland—the call doesn't really know where it's going. Inbound call routing enables the interception of calls, determined by a preset routing rule-set, enabling various actions to be taken for different calls.
