VVX 410 - Losing TLS registration SSPS, Unrecognizable Key errors

[rqphoneadmin]

After rolling out UC 5.9.7.4477 we noticed some of our VVX 410s are losing registration to an Asterisk/FreePBX box using TCP/TLS. Rebooting the phones generally resolves the issue for a few days but the issue returns.

Phone logs show the following:

Hello @rqphoneadmin ,

Welcome to the Poly Community.

I only had a brief look at this and without debugging we cannot really figure out the root cause.

From another internal ticket when

1214095723|sip  |5|00|OnRecvData : Can not decode the packet

This happened to a phone without being registered to a line. The suggestion was to use:

nat.keepalive.interval="20"

I suggest you try these FAQ post:
