Configuring H.323 Gatekeepers and Proxies
H.323 Gatekeeper Configuration Examples
VC-361
Cisco IOS Voice, Video, and Fax Configuration Guide
A priority 0 is assigned to gateway gw1 to exclude it from the gateway pool for prefix 650........ When
gateway gw2 registers with gatekeeper localgk, it is added to the gateway pool for each prefix as follows:
• For gateway pool for 415......., gateway gw2 is set to priority 10.
• For gateway pool for 650......., gateway gw2 is set to priority 5.
To change gateway gw2 from priority 10 for zone 415....... to the default priority 5, enter the following
command:
no zone prefix localgk 415....... gw-pri 10 gw2
To change both gateways gw1 and gw2 from priority 10 for zone 415....... to the default priority 5, enter
the following command:
no zone prefix localgk 415....... gw-pri 10 gw1 gw2
In the preceding example, the prefix 415....... remains assigned to gatekeeper localgk. All gateways that
do not specify a priority level for this prefix are assigned a default priority of 5. To remove the prefix
and all associated gateways and priorities from this gatekeeper, enter the following command:
no zone prefix localgk 415.......
Configuring a Proxy for Inbound Calls Example
In the following example, the local zone sj.xyz.com is configured to use a proxy for inbound calls from
remote zones tokyo.xyz.com and milan.xyz.com to gateways in its local zone. The sj.xyz.com zone is
also configured to use a proxy for outbound calls from gateways in its local zone to remote zones
tokyo.xyz.com and milan.xyz.com.
gatekeeper
use-proxy sj.xyz.com remote-zone tokyo.xyz.com inbound-to gateway
use-proxy sj.xyz.com remote-zone tokyo.xyz.com outbound-from gateway
use-proxy sj.xyz.com remote-zone milan.xyz.com inbound-to gateway
use-proxy sj.xyz.com remote-zone milan.xyz.com outbound-from gateway
Because the default mode disables proxy communications for all gateway calls, only the gateway call
scenarios listed can use the proxy.
Configuring a Proxy for Outbound Calls Example
In the following example, the local zone sj.xyz.com uses a proxy for only those calls that are outbound
from H.323 terminals in its local zone to the specified remote zone germany.xyz.com:
gatekeeper
no use-proxy sj.xyz.com default outbound-from terminal
use-proxy sj.xyz.com remote-zone germany.xyz.com outbound-from
terminal
Note that any calls inbound to H.323 terminals in the local zone sj.xyz.com from the remote zone
germany.xyz.com use the proxy because the default applies.
