We have been using for last many years total 3x Polycom end-points i.e. VSX7000 (with Multi point license) & 2x VSX6000 units & has been working fine.
Recently, we have bought Group 500 for a new office.
When we make a point-to-point call between Group 500 & any other location either VSX7000 or VSX6000, it works fine.
But, when we make Multi point call from VSX7000 to Group 500 & 2 VSX6000, we can see video often pixelating on Group 500. Meanhwile during the multipoint call, VSX7000 & both VSX6000 video call quality remains fine.
I have ckecked & bandwidth is sufficiently available at each end i.e 2 Mbps for each location.
Note: I have set preferred call rate at VSX7000 to be 1800 Kbps & for both VSX 6000 768 Kbps. Once thing is observed that when we make point-to-point call it connects on highest bandwidth i.e. 1800 Kbps but when we make multipoint call, call rate automatically drops to 384Kbps on each endpoint.
