*Call signaling Direct

Gatekeeper Resolved

Gatekeeper Routed

Gatekeeper Routed no RAS

Direct: call signaling information is passed directly between

endpoints. The remote gateway table in the Element

Manager defines a destination code (digits) for each remote

system to direct the calls for that system to route. In each

system, the Nortel IP Terminals and H.323 Terminals

records map IP addresses to specific telephones.

Gatekeeper Resolved: all call signaling occurs directly

between H.323 endpoints. This means that the gatekeeper

resolves the phone numbers into IP addresses, but the

gatekeeper is not involved in call signaling.

Gatekeeper Routed: uses a gatekeeper for call setup and

control. In this method, call signaling is directed through the

gatekeeper.

Gatekeeper Routed no RAS: Use this setting for a

NetCentrex gatekeeper. With this setting, the system routes

all calls through the gatekeeper but does not use any of the

gatekeeper Registration and Admission Services (RAS).

Enable H245 tunneling <check box> If Enabled, the VoIP Gateway tunnels H.245 messages

within H.225. The VoIP Gateway service must be restarted

for a change to take effect.

Default: Disabled.

Primary Gatekeeper IP <IP address> If Gatekeeper Routed, Gatekeeper Resolved or Gatekeeper

Routed no RAS are selected under Call Signaling, type the

IP address of the machine that is running the gatekeeper.

Backup Gatekeeper(s) <IP address>

NetCentrex gatekeeper does not support RAS; therefore,

any backup gatekeepers must be entered in this field.

Note: Gatekeepers that use RAS can provide a list of

backup gatekeepers for the end point to use in the event of

the primary gatekeeper failure.
