Configuration Tasks for IPDC
IPDC is an alternative for MGCP for controlling voice calls through the MGX 8260 Media Gateway.
When using IPDC, you don’t need to configure sessions or backhaul channels.
To configure IPDC, perform the following tasks:
• Switch from MGCP to IPDC
• Set IP addresses and ports
• Configure core settings
• Configure link timers
• Configure COT tones
• Activate the protocol
• View IPDC configuration and status
Switching from MGCP to IPDC
The MGX 8260 Media Gateway supports two call control protocols, MGCP and IPDC. By default,
MGCP is enabled and IPDC is disabled. To switch to IPDC you must change the active protocol type
and reset the chassis.
Warning Switching protocols interrupts service. Perform this operation during light traffic
periods or in a pre-arranged maintenance window.
To switch protocols, follow these steps:
Step 1 Change the protocol type using the chprotocol command, specifying 2 for IPDC; then confirm you
action.
The system automatically reboots.
Step 2 After the system restarts, log in again and verify the change using the lsndinf command.
