[SR-Users] Routing of Audio and Video Stream.

[Joel Serrano]

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
