I’m not sure to be honest. Out of curiosity, why don’t you just pass both streams (audio+video) vía asterisk or rtpengine? I don’t understand why you want to separate them..

In any case, you can always mangle the SDP manually and adjust it as you need, but I don’t know how that will play as one (rtpengine) doesn’t know the existence of the other (asterisk), you would probably have to manage everything manually.... I don’t see it. 

Maybe someone else here can give you a more accurate response... sorry I can’t help anymore

Hi Joel,
Your interpretation of the requirement is correct. Just to stress RTPEngine is there in audio path as I mentioned in point 1 below. So...

User - Kamailio/rtpengine-destination (video)
User - Kamailio/rtpengine-Asterisk (audio)

Later part (audio) is the existing flow. We need to add the first (video)one. Now question is if that is possible?

Thanks

I think he wants to handle rtp like:

User - kamailio/rtpengine - destination (video)
User - kamailio (with/without rtpengine is unclear) - asterisk - destination (audio)

???

Still struggling to understanding the desired flow and outcome...

My assumption of your topology: there's an Asterisk box, some SIP video-enabled phones registered to Asterisk via Kamailio, with Rtpengine as media proxy.

Phone A video calls Phone B. What do you want to happen, drop video, pass it along or something else (not sure what else is possible) ?

Hi Sergiu,

Tendering my apology for the confusion.  This is what is intended. For a call which has both audio video...
1. Audio packets directed towards Asterisk from Kamailio (RTPEngine)
2. Video packets not via Asterisk. RTPEngine directly sends to destination.

Thanks
Abhijit

Hi Abhijit,

Not wanting to remove video contradicts with your original plan "Is it possible to redirect only the audio stream towards Asterisk... and not to send the video stream to Asterisk"

So which one is it?

Regards,
--Sergiu

Hi Sergiu,

Thank you for your help.

If we remove the video m line, I have a doubt if the video stream will still get routed to destination (from Kamailio-RTPEngine).  I do not want the video to be droped from the call. I am learning how to use Kamailio, so excuse me for my limited knowledge of the system.

Thanks
Abhijit

Hello,


I guess you still need to send the INVITE to Asterisk, right?


Cheers,
Daniel

Hi All,

Is it possible to redirect only the audio stream towards Asterisk from Kamailio (Proxy) via RTPEngine and not to send the video stream to Asterisk. I am yet to get the complete reason why my client wants this to happen though.

Thanks
Abhijit
