Using FS10.5 installed from packages on Debian Stretch...

I wanted to replicate the behavior we had with <param name="rtp-timeout-sec" value="300"/> so that we'll hangup calls in which leg B of a conference has sent no media for 5 mins.

I edited our dialplan like this...

<action application="conference_set_auto_outcall"
 data="['conference_member_flags=endconf,jitterbuffer_msec=5p:100p,media_timeout=300000']sofia/gateway/...deleted..."/>

and restarted like this...

fs_cli -x 'fsctl shutdown elegant restart'

But after 8 mins in such a call there was no hangup.

Subject: Re: [Freeswitch-users] rtp-timeout-sec VS media_timeout
For media timeout there are the following chan vars:
media_timeout, media_hold_timeout, media_timeout, media_hold_timeout_video, media_hold_timeout_audio, media_timeout_audio .

They are in milliseconds, not seconds like rtp-timeout-sec . 

<param name="media_timeout" value="300000"/>
