Problem about Trio 8800 with conference

[binh.tran@namlongtelecom.vn]

Hi everyone,

I frequently encounter problems with the polycom device when making a sip call.

About 22 minutes the screen can not see the far site and go to white screen.

Please help me solve this problem.Attached is the image of trio.

Many thanks.

Hello binh.tran@namlongtelecom.vn,

welcome to the Polycom Community and I have moved this into the right section.

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

As this is most likely a Firewall issue I suggest you get your IT team to check what is preventing this.

Hello binh.tran@namlongtelecom.vn,

Your post is still lacking any of the requested details and in addition you did not post any kind of logs for us to look at.

Please raise a ticket via your reseller.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.

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

Best Regards
