A Call Details screen for a call in progress can be launched either by clicking on the “Call Details” button
for a selected call in the Current Calls screen, or by double-clicking on a selected call listed in the Current
Calls screen. The Call Details screen contains general information about the call, as well as details about the
call’s source endpoint and destination endpoint.
Clicking on an
in-progress
call, or using
the “Call
Details”
button, yields
full details
about the call
The Call Details screen consists of three panes: Call General Info, Destination Info, and Source Info. We
describe the fields for each of these panes in a separate table below.
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.
