Chapter 4 Voice over IP Configurations
H.323v2 Dynamic Mapping Configuration
The following configuration shows a Cisco uBR924 router configured for routing mode and using RAS
dynamic mapping with the following characteristics:
• The router’s V1 voice port is connected to a telephone or fax machine with the number 1000, and
the V2 voice port is connected to a telephone or fax machine with the number 1001.
• Four remote dial-peers are configured, with the numbers 1000, 1001, 2000, and 2001. All use the
G.711 Mu-Law CODEC and the RAS protocol is used to resolve their number-address mapping.
(The local dial-peer numbers, 1000 and 1001 are included as remote dial-peers to allow the router
to forward calls between the two local dial-peers, as well as between local and remote dial-peers;
the router must be in routing mode to support this.)
• The cable interface is configured as the gatekeeper interface, using the gatekeeper named
gatekeeper3620 at the IP address 10.1.70.50 and at port 1719. The router identifies itself as the
gateway named uBR924 with a tech-prefix of 1#.
The commands related to the dial mapping are in bold.
