GC3 2-Way Voice with Update

I’ve had my 2gig gc3 panel for awhile now and everytime I accidently set the alarm off someone calls through the panel. I remember reading that 2 way voice doesn’t work on the panel but it was working for me, except the voice is kinda broken up, and if I talk and the central station talks at the same time it cuts out. I know theres an update for the gc3 panel, does that fix this problem?

Two way adjustments are indeed included in the latest Firmware, with a discussion regarding the update and links found here on this thread. We have noticed improvements.
