 |
|
We've been using FS 10.5 for a year or so...with verto for Chrome, Firefox, and Safari on all desktop OSs, and we haven't seen a problem like this before.
0:30 into a call, the mp4 recording of the session starts showing the FS banner. The user is on Safari 14.0.2, macOS Mojave 10.14.6. The log seems fine until suddenly "No video stun for a long time!" appears repeatedly (see below).
The media_timeout should be more than adequate:
<action application="conference_set_auto_outcall"
data="['conference_member_flags=endconf,jitterbuffer_msec=5p:100p,media_timeout=500000']sofia/gateway/[deleted]"/>
The only thing we changed recently that I can think of is that we stopped echoing the video back to verto. But testing across many client combinations hasn't revealed any problem with that.
The only posts I can find that mention this warning are specific to iPhone, but we've had no problem on iPhone/iPad,macOS in general.
Any guesses?
The log snippet...

I don't know if the media_timeout=300 behavior you saw is a bug or not, but I wanted to add my own observation of weirdness about hangup cause MEDIA_TIMEOUT...
I just noticed a conference end abruptly after one leg spoke for 5 minutes. The logs aren't clear why this happened, but it seems that <param name="rtp-timeout-sec" value="300"/> in our sip_profiles/internal.xml is the reason -- it seems that because the *other* leg of the conference remained silent, the RTP timeout was reached.
I couldn't find any confluence pages about MEDIA_TIMEOUT by googling.

Subject: [Freeswitch-users] rtp-timeout-sec VS media_timeout
We had some problems with "hanging channels" for our webrtc clients (via kamailio).To solve the problem I tried to use "media_timeout" setting but it didn't really work. So I tried the deprecated "rtp-timeout-sec" and this actually works fine?
Not working:
<param name="media_timeout" value="300"/>
Working:
<param name="rtp-timeout-sec" value="300"/>
How to reproduce: Make a call using webrtc and just close browser window, after some time freeswitch should close the channel because of missing rtp.
Instead it just keeps writing: "switch_rtp.c:853 No audio stun for a long time!" forever...
Anyway, it works now....just curious why...a typo or bug?
