Use this control to set detection of Media peer inactivity (Inactivity Timeout) which may be used in conjunction with packet loss rate parameter (Packet Loss Threshold) of Packet Service Profile. Note that if Packet Loss Threshold is set to any value less than "400", it is considered as being set to “0” and no packet loss is detected. Thus only Media peer inactivity will be detected by the SBC.

On SBC main screen, go to All > System > Media > Media Peer Inactivity. The Media Peer Inactivity window displays.

System - Media - Media Peer Inactivity

 

The following fields are displayed:

Media Peer Inactivity

 
Parameter

Description

Inactivity Timeout

Specifies the RTP/RTCP inactivity timeout value. The default value is 60 seconds. The valid range is between 20 to 1260 seconds. The timeout value must be a multiple of 10 seconds.

When both RTP and RTCP are enabled, timeout will only occur if both packet types remain undetected for the configured inactivityTimeout duration. If RTCP is not enabled, then only the absence of RTP causes the timer to expire. Specify timeout value in multiples of 10 (range: 20-1260 / default = 60).

  • When using this feature, you must also set the Peer Absence Action flag from Packet Service Profile (see System Provisioning - Packet Service Profile).
  • When Media Peer Inactivity is enabled (configured with an Inactivity Timeout value), SBC detects media inactivity within the configured inactivity timeout value + X, and then executes the configured action (where X is from 0 - 10 seconds).
  • If a valid RTP stream does not send enough packets, use Media Peer Inactivity with RTCP only.
  • If the endpoint does not send both RTP and RTCP packets frequently enough within the Inactivity Timeout duration, Sonus recommends to avoid using Media Peer Inactivity.
