About searches

Before a call can be placed, the endpoint being called must be located. The 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.
The type of search message that is sent depends on whether the call is for SIP or H.323, and whether
the call request was received locally or from an external zone, as follows:
H.323 calls that are placed locally: two messages are sent - the first is an ARQ which locates the
n
device being called, and the second is the call Setup which sends a request to the device asking it
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.
H.323 searches originating from external zones: an LRQ will appear in the Search history page.
n
SIP: a single message is sent in order to place a call: this is either a SIP INVITE or a SIP
n
OPTIONS.
Note that an individual call can have one or more searches associated with it, and these searches can
be of different types. Each search has an individual Search ID; each call has an individual Call Tag
(see Identifying calls).
