Call Details Field Definitions
Field Name Values Description
Call General Info
Call No. Call Number. Accession number identifying a
call in progress.
Cid Sum The conference ID number (CID) is a
unique non-zero value created by the
calling endpoint and passed in various
H.225.0 messages. The CID identifies
the conference with which the message is
associated. Therefore, messages from all
endpoints participating in the same
conference will have the same CID.
Call ID Sum The call ID number is a globally unique
non-zero value created by the calling
endpoint and passed in various H.225.0
messages. The Call ID identifies the call
with which the message is associated.
Call Model direct
OR
routed
Indicates whether the call is direct or
routed.
.
For direct-mode calls, the gatekeeper gives
each endpoint involved in the call the
destination address of the other and establishes
a common call-signaling channel for them to
use during the call. Then the two endpoints
conduct the call without further gatekeeper
involvement.
For routed-mode calls, the gatekeeper
establishes a connection between the two
endpoints but keeps itself involved in call
signaling for the duration of the call. In routed
mode, the gatekeeper keeps a call-signaling
channel open for the entire duration of the
call. As a call-management service, the
gatekeeper can change the routing of the call
(by line hunting) while the calls is in progress.
If the gatekeeper is to implement
supplementary (H.450) services, it must
operate in routed mode.
