Configuring Gateway Control Protocols
Complete the following steps to configure gateway control protocols.
Note Use the configure gateway control CLI commands in this section only if you need to configure
argument values for the commands that are different than the default argument values.
Step 1 Type the cnfxgcppeer command, mgc-num, protocol-num, and remote-udp-pnum, and press Enter to
configure a port number for a particular call agent and protocol. The port is used to send
gateway-initiated messages to the call agent. Specify the arguments with the following values:
• mgc-num: In the range 1 to 8.
• protocol-num: A protocol number which is displayed by using the dspmgcgrpprotocols command.
• remote-udp-pnum: The remote UDP port number used for MGCP/SGCP protocol communication
with the call agent.
Step 2 Type the cnfxgcpmwd command, max-wait-delay argument value, and press Enter to specify the
maximum waiting time before a Restart in Progress (RSIP) message is sent to the call agent. Specify the
max-wait-delay argument value as follows:
• max-wait-delay (maximum wait time; defined in milliseconds): In the range from 0 to 600000;
(default = 10000; 10 seconds)
Note The max-wait-delay argument value sets the maximum wait time for the entire VISM
card, not for a particular call agent.
Step 3 Type the cnfxgcpretry command, min-vtoca-tout, vtoca-retrans-num, and |max-vtoca-tout| argument
values, and press Enter to specify the VISM minimum and maximum wait time, and number of retries,
for a call agent message acknowledgment. Specify the arguments with the following values:
• min-vtoca-tout (defined in milliseconds): In the range from 1 to 100000; (default = 500)
• vtoca-retrans-num:
–
Default = 3
• |max-vtoca-tout|: In the range from 0 to 100000.
Step 4 Type the cnfxgcpbt command, network-type, vc-type, and aal-conn-type argument values, and press
Enter to specify the type of bearer channel VISM uses, if one is not specified by the call agent in
protocol local connection options. Specify the arguments with the following values:
• network-type:
–
1 = IP
–
2 = ATM
• vc-type:
–
1 = PVC
–
2 = SVC
