Hello,

 

I hope someone can help me with an issue with my phones.

 

I have VVX 310s, and recently the screen goes white with the error "Not Registered" appears on the screen. It lasts for about 10 seconds and the phone is back to normal. It even happened when I was on the call, but the call was not dropped. This has been happening multiple times throughout the day, and to mulitple phones.

 

I have firmware 4.1.8 with SRTP enabled on the phone. Anyone has an idea what the issue is with the phone? is it a faulty phone?

Hello truong.kha@8x8.com

welcome to the Polycom Community.

 

Why would the phone be defective if it works ?

 

The message is simply telling you that the phone has lost it's registration. Once it re-establishes it again the message will disappear.

 

The message is telling you that there is a problem with the registration to the server that you should investigate.

The community's VoIP FAQ contains this post here:

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

Resolution: Please check => here <=

 

and

 

Apr 23, 2013 Question: How can I setup SRTP / Secure RTP?

Resolution: Please check => here <=

 

The above FAQ post's show you how to troubleshoot this and you can then work with your SIP provider on how to action that the registration is no longer lost.

 

Maybe simply shorten the registration Interval. Have a look in the Admin Guide for reg.x.server.y.expires

Hello Steffen,


Thank you for your response!

 

I thought of that and checked before posting my question to the forum. On my server, I do not see the phone losing registration, and as mentioned in my post as well that it happened while the user was on the call, but the call was not dropped.  It has been happening multiple times during the day so far.

Hello truong.kha@8x8.com

you may want to look at the basic's of SIP for example explained => here <=

 

In order to make a call you send SIP messages between the Phone / Server. The phone usually registers to a Server but you can also make simple IP calls.

 

Once the call is established there is usually no requirement to send further messages (all depending on the setup / scenario) and the RTP / SRTP flows between the two phones / servers.

 

Just because the call is still up does not mean the phone needs to be registered.

 

You need to do a bit more troubleshooting based on the above linked FAQ posts or other sites that can be found via Search engines and after exhausting these raise a case via your Polycom reseller or with who looks after your server.
