>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>    Affects Versions: 13.8.0
>            Reporter: Jacek Konieczny

> WebRTC Video calls to app_echo work for me, but calls to other PJSIP endpoints do not – the browser is not able to decode the video. Video sent by the browser is properly decoded on the other side (linphone).
> I found out, that my Firefox cannot decode video due to cleared 'Marker' bit in incoming RTP packets (marker should be set on the last packet of each frame).
> This seem similar to ASTERISK-25451, -but seems to affect WebRTC/SRTP/DTLS media only-.
> I will try to investigate this further.
