Hi,<div> I am using sip accounts from <a href="http://opensips.org" target="_blank">opensips.org</a> for testing. using TCP as sip transport.</div><div><br></div><div> I find server changes the "c=" line to server's public address, and this make ice mismatch because the server public address is not in ice candidate list. Is it normal? Any suggestion.</div>
