Extensions cannot pickup a call to page group

[correlative]

Hello,

I'm on 3CX Professional Annual v16.0.676
Extensions are behind a local SBC and the 3CX instance in located in a colo facility.
Phones are Yealink T21P E2

I have a page group setup at extension 800. All the relevant extensions are there. When I try and page, all the extensions can hear the page but no one can pick up. I checked the page group permission and the individual permissions and they all seem in order. Any ideas as to what's going on?

Intercom to an extension (*9XXX) works without any issue.

Thanks

What do the logs say? What does the phone say?

phone doesn't say thing other than showing its on an intercom call.

which logs should I be looking at and where are they located?

LOGS HERE: log in to management console and look at the activity logs.

But - Page Groups, AFAIK, are just for Paging.

"John, you have a call on Park 1"
"John, call Angie at ext 1234"

I do not think it is meant for any 1 individual to answer the call. It is one way.

Paging is one to many - one way
Intercom is one to one - two way

Thanks I see that but thats kind of odd. In every other phone system I've used, someone can pick up a page. Lets say you are looking for someone in a facility, you quick page and ask then to pick up and then they can pick up from the closest handset and answer you.
