Poly VVX450

IgorLi · ‎04-14-2026

Hello,

Does anyone had the same issue:

Devices randomly go down as "Not Registered".

VVX450 phones are connected to the Meraki switch and then to the Fortinet firewall.

Thanks

Hello @IgorLi ,

Welcome to the HP community.

Unfortunately, your post does not contain the currently used Software version for the HP Poly product,

In addition, we are unaware if this device is running Poly UC Software or ObiHai

This is important, especially in the future, when someone finds this post in days, months, or years.

Please do not simply edit the original post but reply with the versions.

In the FAQ or the Read 1st section, we remind users why this is important.

From the same FAQ :

Oct 17, 2011 Question: How can I change Logging Levels or use Syslog?

Resolution: Please check => here<=

Jan 19, 2012 Question: How to troubleshoot Poly VoIP-related Issues?

Resolution: Please check => here <=

If no other volunteers reply, I suggest you contact our Support organization in your region. Details are in my Signature.

Best regards

Steffen Baier
