Paging Group 631 enables a user to page all the phones/extensions in the group.
It works great, except that any party that is receiving the page, can TALK BACK.
This is causing a privacy concern, because even if a user is just having a plain discussion in their office, while someone is paging, and their voice can be heard all over as a TALK BACK...
It seems ALL phones that are being PAGED go into an INTERCOM mode on SPEAKER PHONE, which means all audio can be heard back.
