Yeastar is it possible to call a group of numbers at the same time?

Question

Telephony

Good afternoon! Is the following scenario of using ata yeastar s20 possible:
there are no incoming lines.
10 internal numbers, let's call them detectors for simplicity. snom pa1 are used as subscriber equipment.
2 internal numbers, let's call them reception for simplicity. Ordinary telephones are used as subscriber equipment.

Is it possible to call all 10 detectors at once? From the description of call groups, I understood that they are not suitable, since all snom pa1 will pick up the phone ...
How other functions (conference, etc.) work is not clear to me. So I don't know if they will fit or not.
Tell me is this real? And what is the name of this function :)
Thank you!

Answer 1

The function you need is called Paging/Intercom or according to our GGS.
snom pa1 is just for this and made for GGS. A speaker is connected to it, which will notify.
It works simply, find Paging / Intercom on the PBX, assign the number of this group, put all the numbers on which sit snom pa1 into this group. Call this number and the swearers from this group will turn on at once and will broadcast whatever you say.
