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 will depend 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:
•
For H.323 calls that are placed locally, two messages are
sent: the first is an
ARQ
which locates the 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 will be associated
with a particular call.
•
For H.323 searches originating from external zones, an
LRQ
will appear in the
Search history
page.
•
For SIP, a single message is sent in order to place a call: this
will either be a SIP
INVITE
or a SIP
OPTIONS
.
Each search has an individual
Search ID
; each call has
an individual
Call Tag
(see
Call IDs, Serial Numbers and
Tags
).
