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 maximum-call-duration parameter governs MGCP call activity and sets the absolute maximum length of a call. When a call exceeds this parameter setting, the MGCP ALG tears down the call and releases the media sessions. The default setting is 432000 seconds, and the range is 180 through 432000 seconds. This setting also frees up bandwidth in cases where calls fail to properly terminate. In this example, the call duration is set to 180000 seconds.
