Meeting in interruption v.2


We have HDX 6000 System with one public IP Address, there is no firewall or NAT device.

We make video conference meeting and the meeting is disconnected after 41 minutes.

I called to Japan site, after 41 minutes, meeting is out.

I called to another VN site (using vsx-6000), everything is ok.

 I checked "TCP Keep Alive" on HDX-6000, it's 30 minutes and there is no router after this System. So I don't think root cause is about TCP Timeout or TCP Keep Alive.

I have no place to say anything now!


Japan site is using "Codian MCU 4220/4.1(1.59)", does anyone here know this device?

Is there any configuration on MCU can make meeting be interrupted? 


Plz see the attachment for more detail.

Hello suyenpham,


I am unsure why you felt the need to split your new post from your original post => here <=


Both Pete and Frank had pointed you towards your router or network infrastructure but as far as I can see any changes made or checked from your end only involved the endpoint.


Please be aware that the community is not a replacement for the Polycom Support structure and this may be the point for you to engage your Polycom Reseller for support or to raise a support Ticket with Polycom directly so you can receive professional support for your individual problem.


Best Regards
