I am trying to create paging based instant conference with FreePBX 14 between 6 Cisco SPA303 phones, located in 2 rooms. The results are horrific due to the audio feedback from the phones in the same room.
So I’ve been thinking, is there a way to configure the system in a way that all of the phones in the first room transmit voice only to the phones in the second room and vice-versa? Or in other words, duplex communication but not between all of the phones, but between different groups of phones.
Or is there a better way to achieve this?
