Origin / Edge configuration with cRTMPServer and Wowza

Hello.

We have a partner who is streaming their live content using cRTMPServer and we are using Wowza. I was wondering if its possible to do a origin/edge configuration with this setup, using Wowza as the edge. We are trying to limit the amount of bandwidth utilization (and we have a couple dozen channels) so it makes sense to “start” the stream only when accessed by the user which origin/edge configuration should offer.

I tried the following config in Application.xml:

StreamType = live

with OriginURL = rtmp://sourceserver/app

and

StreamType = liverepeater-edge

with OriginURL = rtmp://sourceserver/app

But this is not working. Any suggestions to get this to work, without ingesting the stream from the origin 24/7?

Thanks.
