"Inbound TLS Negotiation Error"

I'm seeing this message on our VCS-C (v.7.2.3) concerning a Polycom HDX 8000 codec. The source port changes, but the DEST port remains 5061. A reboot of the codec appears to make the log message disappear.

Has anyone seen this or have an explanation?

Per the Cisco Deployment Guide the HDX is to register via TCP and not TLS.

Setting the Transport Protocol to TCP rather than Auto has stopped this message.
