Wasn't sure if this should go here, or the VoIP, or router forum.
I have a Fritz!Box 7390 sitting behind my main router. Fritz is configure to "share an existing Internet connection", so is just on the network for VoIP.
I wish to setup QoS on my main router, but when I examine the VoIP traffic I notice that traffic originating from the Fritz isn't tagged as DSCP 24 & 46 (SIP & RTP).
How do I get the Fritz to tag the outbound VoIP traffic?
