Meeting in interruption v.2

[suyenpham]

Hi,

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
