Cisco UBE Gateways and Attendant Interworking


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.
