Cisco uBR924 Software Configuration Guide

Chapter 4 Voice over IP Configurations
H.323v2 Static Bridging Configuration
Note The ID numbers assigned using the dial-peer voice command must be unique but they are local to the
Cisco uBR924 router. These numbers are used only when configuring each particular dial peer and have
no meaning when dialing numbers or routing calls.
The following example shows a Cisco uBR924 router set up to support bridging and a static H.323 dial
map with the following characteristics:
• Voice port V1 is connected to a telephony device that receives calls for the number 4123.
• Voice port V2 is connected to a telephony device that receives calls for the number 4124.
• Outgoing calls to the numbers 6000—6999 are routed to the dial peer at IP address 10.1.71.65.
• Outgoing calls to the numbers 7000—7999 are routed to the dial peer at IP address 10.1.71.75.
These calls are sent with an IP ToS precedence of “5” and using the G.711 Mu-law codec algorithm.
The commands that set up the H.323v2 dial map are shown in bold:
version 12.1
no service pad
Step 8
uBR924(config-dial-peer)# port 1 Specify that voice port V2 is attached to this
telephony equipment.
Step 9
uBR924(config-dial-peer)# dtmf-relay [cisco-rtp]
[h245-signal] [h245-alphanumeric]
Optionally configure the dial peer to support out of
band signaling of DTMF tones.
Step 10
uBR924(config-dial-peer)# exit Exit dial-peer configuration mode.
Step 11
Repeat for each possible outgoing destination:
uBR924(config)# dial-peer voice id-number voip
Specify a unique id-number for this outgoing
dial-peer and enter dial-peer configuration mode.
Step 12
uBR924(config-dial-peer)# destination-pattern digits Specify the telephone number(s) associated with this
dial-peer.
Step 13
uBR924(config-dial-peer)# session target [ ipv4:ipaddress |
dns:hostname ]
Specify the destination IP address or hostname for
this dial-peer. This could be the IP address or
hostname for either an IP telephone or another router
or host providing voice services.
Step 14
uBR924(config-dial-peer)# ip precedence number (Optional) Specify an IP packet precedence level
(1-5) for packets carrying calls to this dial peer (1–5,
where 5 is the highest precedence for normal IP
flows).
Step 15
uBR924(config-dial-peer)# code [ g711alaw | g711ulaw |
g729r8 ]
(Optional) Specify the codec algorithm to be used
for these calls. The default is g711r8 (8Kbps
compression; A-Law and Mu-Law are 64Kbps
compression).
Step 16
uBR924(config-dial-peer)# dtmf-relay [cisco-rtp]
[h245-signal] [h245-alphanumeric]
Optionally configure the dial peer to support out of
band signaling of DTMF tones.
Step 17
uBR924(config-dial-peer)# exit Exit dial-peer configuration mode.
Step 18
uBR924# copy running-config startup-config
Building configuration...
Save the configuration to nonvolatile memory so
that it will not be lost in the event of a reset, power
cycle, or power outage.
Step 19
uBR924# show startup-config Display the configuration file that was just created.
