Hello.

We have 2 licensed wowza servers. Origin and edge.

We have 2 channels between them: inner and outer (by inet).

According to [this arcticle](http://community.wowza.com/t/-/34720)I want to use our channels from the StartupStreams.xml to solve problem with Request Timeout on cupertino stream.

Sometimes our inner channel down and we’ve use outer channel.

What I have to read in \*.stream file that wowza automatically switches from inner channel to outer channel?

For example:

in my StartupStreams.xml:

live/_definst_

rtp

myChannel.stream

in \Wowza Media Server\content\myChannel.stream:

rtsp://inner\_ip:1935/app\_name/myChannel

rtsp://outer\_ip:1935/app\_name/myChannel

Is it right metod or I need to use another one?

Thanks a lot!

Hi Denis,

I think stream failover in a .stream file only works for live-repeater, but not for rtsp according to my test.

At present this is the way to achieve failover:
