Media Relay and "no-voice"

I installed Xeepe one week ago with default Media Relay settings. All was OK.
Later I wanted to test Media Relay with port forwarding in according with your Guide. Also I had successful voice conversations with external SIP clients.
Now I have switched back to default STUN mode of Media Relay and cannot hear voice anymore!
Is it a bug?

Remove port forwarding rule for Media Relay from your router.

Hope it will help.

Possibly it must be moved to FAQ or included to documentation

Thanks

Now it works
