Cisco UBE Gateways and Attendant Interworking
When you’re interworking with gatekeepers, Cisco UBE can be acclimated in two ways. First, it
can annals with the gatekeeper, agnate to a accepted Cisco IOS gateway.

Note Cisco UBE and a attendant can be deployed on the aforementioned router, as continued as CPU
and anamnesis requirements are met.
In addition, a attendant can use a registered Cisco UBE router with via-zones. This
means that back acquisition a alarm amid two zones, a attendant can be configured to
route the alarm via a area absolute a Cisco UBE router. This enables interzone networking
using a axial Cisco UBE router after the charge to arrange a Cisco UBE router at
every armpit or redesign an already-deployed H.323 network.
Figure 9-8 shows how a Cisco UBE is chip with attendant deployments.
Consider the afterward architecture guidelines for Cisco UBE aperture and gatekeeper
implementations:
■ Back a Cisco UBE router is acclimated as an outbound articulation gateway, the aforementioned concepts
that administer back application acceptable articulation gateways with gatekeepers administer to Cisco
UBE deployments.
■ Back acquisition calls amid zones that crave Cisco UBE functionality, via-zones
should be used. Existing attendant deployments can calmly be adapted to include
Cisco UBE application this concept.
