Issues with STUN server

[Cool04ek]

Hello, firstly I would like to thank you for this great framework. It has a lot of useful settings and features.
However, I've faced a pretty significant issue.
If client device is a part of local network under NAT, there is no sound during the call. As far as I understand, it happens because app fails to establish proper connection with STUN server and retrieve proper IP and port. I've tried providing different STUN servers for the app, but result is the same.
On the other hand, IOS version seems to work fine, also it relies on the same lib underneath.
Below I have provided screenshots with SDP for IOS and Android:

As you can see IOS provides proper port and Android provides default, it should not though.

If you have any ideas why is it so, please contact me.
Thank you in advance.

Hello,
Thanks for reporting this problem, on which version of Linphone-Android did you test ?

I was testing ## [3.2.4] - 2017-01-19
And also checked application from Play Market.
For now we have resolved this issue through our backend, but global IP and port are still wrong.
