Hello Peter,

Calls get established at the signaling level, no matter which network or 
client. So I can leave Kamailio out of the equation. Also did some more 
testing and can make calls between two sipml5 clients on different networks.
Regarding Boghe/IMSDroid, the devs at the company where I work are very 
familiar with that framework so we'll figure that out. I'll do some 
reading about ICE. No way it could be integrated like rtpproxy?
