Thanks Carsten.

Please correct me -

So we need to make sure for video UA1 and UA2 should talk with each other with same codec, since SEMS can only relay video packets unlike audio which it can transcode. 

Moreover, just a curiosity, can it be configured so that video packets flow between RTPEngines (UA1 <=> RTPEngine1 <=> RTPEngine2 <=> UA2) whereas the audio takes the route via SEMS.

Thanks
Abhijit

Hi,

it depends on your configuration, e.g.:
- if you enable RTP-Relaying, then of course the flow for RTP would be UA1 <=> RTPEngine1 <=> SEMS <=> RTPEngine2 <=> UA2
- if you enable Transcoding (this forces RTP-Relaying to be active), it's the same

If you don't use any of these options, then SEMS will do signalling only, so the flow for RTP would be UA1 <=> RTPEngine1 <=> RTPEngine2 <=> UA2....

Thanks,
Carsten

Thanks Carsten and Mojtaba.

I will need inputs/comments from you regarding the following scenarion.

UA1 ----------------  Kamailio/RTPEngine (Proxy1) ----------  SEMS ------------------ Kamailio/RTPEngine (Proxy2)-------- UA2

If UA1 makes a video call (webrtc etc.)  how, the media will flow. 
  1. Audio (RTP)  will traverse UA1 - RTPEngine1- SEMS - RTPEngine2-UA2
  2. Video (RTP) ? will it be via SEMS or that can be bypassed
Thanks
Abhijit

Hi,

just another note:
SEMS can forward Video-RTP Packets (but nothing beyond that).

It's gotten a bit quiet on the SEMS-Project, but I don't think it's completely dead...

Thanks,
Carsten

Hello,
I've never heard that SEMS Support video, But I just know if you switch enable_rtprelay's option off, It would  works as p2p.
So using these feature of SEMS is optional and you could keep using SEMS with no worry!

Hi All,

Is the development work for SEMS server still on or stopped? Does it support video?

Thanks
Abhijit
