I am having a major issue with 3CX V20 (Hosted by 3CX) and my Polycom VVX401/201 phones. We have a SBC running on a local server and the 3CX is hosted by 3CX on the cloud. It is the Enterprise version with 8 SC's.

With V18 everything worked fine. With V20 Suddenly, on my Poly VVX401 and 201 phones, the Multicast PA no longer works.

Pre V20, the phones would show (on the Web Interface) under Group Provisioning:
Group Type, Group Number, Available, Send, Receive, Subscribe and Label.
Marked "YES/NO" as appropriate

Now, with the V20 provisioning, It only shows Group Type. Group Number and Available are there, but greyed out and can't be modified. The rest don't even have Send, Receive, Subscribe and Label Available! (And since Subscribe is not "YES" then the Multicast will not work) The only way to get them back is to reload the phone with a default configuration from Polycom. As soon as I provision the phone from 3CX, it all stops working again.

We are a school and we must use multicast for our bell system to ring the phones in each classroom and on the Admin's desks.

Any ideas/help/people I can speak with. I have started calling support partners, but so far, none of them want to work with us (yes, I offered to pay the hourly rate) because we don't use them for hosting.

THANKS!

Yossie
