MGCP ALG Configuration Overview

The Media Gateway Control Protocol (MGCP ALG) is enabled by default on the device—no action is required to enable it. However, you might choose to fine-tune MGCP ALG operations by using the following instructions:

1. Free up bandwidth when calls fail to properly terminate. See Example: Setting MGCP ALG Call Duration.

2. Control how long a call can remain active without any media traffic. See Example: Setting MGCP ALG Inactive Media Timeout.

3. Track and clear signaling traffic when it times out. See Example: Setting MGCP ALG Transaction Timeout.

4. Protect the media gateway from denial-of-service (DoS) flood attacks. See Example: Configuring MGCP ALG DoS Attack Protection.

5. Enable unknown messages to pass when the session is in Network Address Translation (NAT) mode and route mode. See Example: Allowing Unknown MGCP ALG Message Types .
