Using a Standalone Cisco IOS Gatekeeper

Polycom, Inc. 101

Figure 7-2 Example configuration for standalone IOS gatekeeper.

! - One network interface (Ethernet or Loopback) must be designated as the source interface.

! - This ensures that all H.323 gatekeeper traffic originates from the same address for each call.

interface FastEthernet0/1

ip address 10.232.253.253 255.255.255.0

h323-gateway voip interface

h323-gateway voip bind srcaddr 10.232.253.253

! - The command "gatekeeper" puts the router into GK configuration mode

gatekeeper

! - The first local zone created must contain the IP address of the network interface on the

! - IOS device to which H.323 has been bound. This establishes the address of the gatekeeper.

! - The zone name and domain name are requirements for each zone to help the GK manage

! - endpoint registrations properly. The "enabled-intrazone" is required to allows devices

! - in each zone to call each other. The zone use for Polycom devices must be listed

! - first as Polycom devices do not understand zone names.

zone local video company.com enable-intrazone

zone local cucm company.com

! - Zone prefixes are required to properly route calls into CUCM as CUCM does not register

! - E.164 prefixes or extensions.Therefore, by adding a zone prefix, we are telling the GK that

! - any Call Admission Request (ARQ) looking for an extension starting with 1, and is x digits

! - long, gets routed to the CUCM zone, and eventually the CUCM itself. A "*" represents a

! - multiple digit wildcard match (i.e. 123456). The use of the "*" is required as the IOS GK

! - uses this to route all cucm zone calls to the registered CUCM cluster.
