Hi, first of all, sorry for my english 😉


So, we have an issue with a Polycom HDX 7000 during a 3-way call.

The first call works well, but when we call the second device, the screen from the first call goes black...

Audio still works, but there's only video from the second left, and we have to call the first one again in order to get the video back.

The HDX is behind a ZyXell firewall and we think that it's probably the source of the problem, since we tried to connect the HDX directly to the router and it works fine.

Can someone help us ? Maybe some port issue ?

Thanks 🙂
