Since your subject says without SIP signalling update, no. The phone needs to detect its IP change and tell FS.<div><br></div><div>FS needs to know where to send signalling messages to as well as media - ringing, answer, hangup etc. That means it needs to know the new IP &amp; port for the SIP part too.</div>

<div><div><br></div><div>The closest to what you&#39;re asking is RTP auto-adjust, which is a workaround for devices unable to handle NAT correctly. But I don&#39;t think it should allow it mid-call, or that could allow someone to hijack your phone call.<div>
