media-manager guard-timers

Hi,

 

We would like to terminate the SIP call by ACME if on client side there is a connectivity issue (either network goes down, loss of wifi signals or battery goes down) occurs and RTP flow stops.

 

For this purpose under media-manager object we set the timers as below;

 

        flow-time-limit                86400
        initial-guard-timer            300 
        subsq-guard-timer              300
        tcp-flow-time-limit            86400
        tcp-initial-guard-timer        300
        tcp-subsq-guard-timer          300

 

I expect when the issue occurs ACME will terminate the call after 300 second (because of subsq-guard-timers) . While doing some tests (A and B party are on the same SBC and same realm) we observed that termination is not happening after 300 seconds. Any idea what could be the reason? Is there any other parameter that could override this parameter?
