Requirements

Before you begin, determine the type of parameter used to control the MGCP call activity and manage its network resources. See Understanding MGCP ALG Call Duration and Timeouts.

Overview

The transaction-timeout parameter governs MGCP call activity and is a signaling message; for example, a NTFY from the gateway to the call agent or a 200 OK from the call agent to the gateway. The Juniper Networks device tracks these transactions, and clears them when they time out. The timeout range for MGCP transactions is from 3 to 50 seconds, and the default is 30 seconds. In this example, the transaction timeout is set to 20 seconds.
