Note The above configuration assumes that the DHCP server assigns an IP address to the cable interface that
is in the class A private network (10.0.0.0).
H.323v2 Dynamic Mapping Configuration
When using a Cisco IOS image that supports voice, the Cisco uBR924 router supports using the
Registration, Admission, and Status (RAS) protocol to allow a remote gatekeeper to translate phone
numbers (E.164 addresses) to the IP addresses of specific dial peers. This allows the gatekeeper to
maintain a central database of dial peers, so that this information does not have to be entered into static
dial maps on every router that is acting as a voice gateway.
Note The Cisco uBR924 router can use H.323v2 dynamic mapping in either DOCSIS-bridging mode or
routing mode.
