About searches
Before a call can be placed, the endpoint being called must be located. The Cisco VCS sends and
receives a series of messages during its attempt to locate the endpoint being called; these messages
are each known as searches. An individual call can have one or more searches associated with it, and
these searches can be of different types.

are each known as searches. An individual call can have one or more searches associated with it, and
these searches can be of different types.

the call request was received locally or from an external zone, as follows:

to accept the call. Each message shows up as a separate search in the Search history page, but
only the Setup message is associated with a particular call.
