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

Indicates whether the call is direct or

 

OR

routed. .

 

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.
