I have mobile applications running behind NAT. When their reachability changes (and the device's local route updates), I want to automatically switch the RTP stream to the new address/port combination. I've tried using the RTP ALWAYS_AUTO_ADJUST bug, but that results in *very* choppy audio. I also don't really need it, as the only time I care to perform RTP auto-adjust is after an invite session. For this case I can safely assume that the client *will* send a re-invite when its address changes. Is there any way to perform RTP audio adjust only on a re-invite? Using STUN doesn't seem right for two reasons: 1) on its own it can't solve this problem (even if it determines the external IP, the port is still wrong). 2) it results in issues on FS "Invalid STUN/ICE packet received 20 bytes" Would appreciate any help. Best, Colin
