Typically that's caused by your ATA or SIP device not getting the response from the sipsorcery server. The register request you're seeing in the logs is coming from your device. Try restarting your SIP device and if that doesn't solve it then also your router.

After factory reset my SPA 3000 and tune the figure one by one, I found the problem. If I set "NAT Mapping Enable" to "No", then it will keep registration stably rather than cycling registration.
