Understanding SCCP ALG Inactive Media Timeouts

The inactive media timeout feature helps you to conserve network resources and maximize throughput.

This parameter indicates the maximum length of time (in seconds) a call can remain active without any media traffic within a group. Each time a Real-Time Transport Protocol (RTP) or Real-Time Control Protocol (RTCP) packet occurs within a call, this timeout resets. When the period of inactivity exceeds this setting, the gates the Skinny Client Control Protocol (SCCP) opened for media are closed. The default setting is 120 seconds, and the range is from 10 to 2550 seconds. Note that upon timeout, while resources for media (sessions and pinholes) are removed, the call is not terminated.
