Setting SCCP Inactive Media Timeout

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 (RTP or RTCP) traffic within a group. Each time an RTP or 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, 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.

Note: You must use the CLI to set SIP-signaling and media-inactivity timeouts.

To configure inactive media timeout, use either the J-Web or the CLI configuration editor.
