Only get successful local (host) and relay (turn) calls?

[esoinila]

We have a CoTurn installed on (believe it or not, Azuré, it worked with the AWS settings (was not supposed to work according to google search, it felt like sailing of the edge of the known World map to go against google-search wisdom)). 

We can make these local "host"-candidate calls in: 

• mediaserver (a consumer style high-end wlan (zyxel 1608) default settings, with public static IP). 
• mobile android shared wifi net (huawei honor 8 lite)
• could not make these without TURN in the office-network, but with turn these worked 
  

We can also make calls between clients in these different networks. However, for all the variations of making calls between these networks we have observed that "relay", i.e. TURN server is always used (based on cloud bandwidth logs). Now I understand that TURN is needed when the office-fire-walled network is used but surely there should be some successful STUN-calls somewhere? 

Is this lack of srflx-candidate successes normal ? If so, then how is it possible to have statistics of 85 % of all WebRTC-calls connecting with just STUN without TURN advertised on the net ?  Do they count local network host-connections to this figure and are there so many of those then?

Included are Tricle ICE listings from all these networks.

I have the same in a strict network server, you must change something in the firewall I guess (doubt you have much control in Azure :P)
