• Configure MGCP core parameters
• Configure default call setup parameters
• View MGCP configuration and status
Switching from IPDC to MGCP
The MGX 8260 Media Gateway supports two call control protocols, MGCP and IPDC. By default,
MGCP is enabled and IPDC is disabled. This procedure explains how to switch back to MGCP from
IPDC.
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 1 for MGCP; then confirm your
action. The system automatically reboots.
Step 2 After the chassis restarts, log in again.
