Hi all. Looks like a very helpful group here [Linked Image from sundance-communications.com] I just signed up for access to the manuals, but I'm unable to find what I'm looking for.

Our boss is interested in being able to press an intercom button and the receiving station simply switch on (speaker phone). I've used a Lucent based phone system that had this capability before, which was referred to as "barge in" or something like that. I'm curious if this Prostar system had the same capability.
