Ext. H.323-GK 
 


Settings | Network | EXT H.323-GK
 
Ext. H323-GK (external H.323 gatekeeper) is used by the HiPath system to register itself via the H.225 RAS as a gateway for an external gatekeeper.

10.10.16.1  

External H323 Gatekeeper Mode flag 
Parameters for operation with an external H.323 gatekeeper can only be specified if this flag is activated.
Project-specific release is required for the "External H.323 Gatekeeper Mode" flag. An exception to this rule is made for simplified configuration of a third-party node (for example, HiPath 4000) without registration ("Perform Registrar" must be deactivated).

10.10.16.2  

Area: Gateway 

Environment  
Since an external gatekeeper may involve various signaling options, the external gatekeeper is specified via this parameter. You can choose between
   -   HiPath 4000
   -   a CISCO Gatekeeper (enabling is exclusively project-specific)
   -   a connection to SURPASS
   -   or one OpenScape Voice

Trunking Mode  
The trunking mode affects the H225 call signaling, i.e., the transmission of feature-specific information . You can choose between
   -   H323 Native: no transfer of feature-specific information
   -   H323 Annex: Feature-specific information is transferred

Station number  
The "Public Directory number" is configured here as in the case of the system number. The gateway in the own system can be reached under this number.

Time to Live  
Validity period for the registration, specified in seconds. Within the time period set here, the gateway registers itself cyclically at the external gatekeeper.

10.10.16.3  

Area: H.323 Security 
This area is currently not yet supported by the system.

10.10.16.4  

Areas: Primary/Secondary Gatekeeper 
The gatekeeper identity (GK-ID) of the external gatekeeper must always be entered. If it is omitted or is subject to errors, the registration of the gateway is rejected.

IP address  
IP address of the external gatekeeper.

Port  
Port number of the external gatekeeper.

GK-ID  
Name of the external gatekeeper.

10.10.16.5  

Perform Registrar 
The system registers at the gatekeeper if this flag is activated. If this flag is deactivated, registration is not performed (for simplified configuration of a third-party node, such as, HiPath 4000).
