The question to ask is : what is the network topology ?

For each of the networks : does the network does support IPv4 only, IPv6 only, or both ?

We (users helping with troubleshooting) would need app logs to dig further, especially on the STUN processing.

At first sight, it seems that something should be looked-at regarding the England mobiledata network behaviour.

Also, does your Kamalio server handles IPv4 NAT aware media-relay ?

I have a problem on 5G network,
We downloaded Linphone App(V5.1.62) on Google play for test
Our Sip Server : Kamailio
Ice enabled

Test scenario
User_1(on England, on MobileData)   calling to User_2(on Turkey, on  Wifi  ), there is no media establishment  ( closing in 30sec)
User_1(on England, on MobileData)   calling to User_2(on  England  , on  Wifi  ), there is no media establishment ( closing in 30sec)

User_1(on England,  on  Wifi)   calling to User_2(on  Turkey  , on  Wifi  ), works fine
User_1(on England,  on  Wifi)    calling to User_2(on  Turkey  , on  MobileData), works fine

There is any solution for this problem?
