VVX 410 phones sending Welcome tone


Hoping someone may be able to help. We have deployed over 300 VVX 410 phones to a customer and approximately 15 phones,periodically will produce the "welcome" tone or "reboot" tone however phone never reboots however I get a messagfe on the top corner that says network down however phone comes back on line after a few seconds and phone is ok. It never fully reboots however it does appear the phone is down for the short period. We first were notified about this from the customer however they didn't say it interferred with the call.


Any Ideas?

Re: VVX 410 phones sending Welcome tone

Hello Eric,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

Please also include if you are using a SIP server or a LYNC / Skype for Business server.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


Did you check the logs on the phone to see why the network was lost?

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
