Chrome Version       :  60.0.3112.113 
OS version           :  Windows 7 Service Pack 1
Network              :  Cable

Video issue, Audio issue, both, neither? Video
Flash or HTML5?  HTML5


What steps will reproduce the problem?

(1) use JSSIP (https://tryit.jssip.net/) and registered it to a Kamailio proxy server
(2) make another classical SIP client also register to the server
(3) take turns making calls each other several times
(Until now I cannot find the exact reproducible steps)

What is the expected result? 
- the media streams just work normally.

What is the actual result? 
- some times after call started for seconds, JSSIP side got a frozen frame and not 
  recover unless you hangup it and start a new one.

Any additional information (anything else which may help us debug the
issue)?

- I checked whether JSSIP side did receive the video SRTP stream or not by capturing the packets,
  but the packets showed that the browser indeed obtained the media contents,
  then I just wonder if it's the issue of the decoder the browser used.

log files as attached.
Please inform me if any other information is need.

Thanks. :)
