I have one of the Original BCM units, running 3.7. We have a nortel doorphone at shipping to call us when delivery's arrive. We have a strange effect happening where if you press it once, we get the page tone in 4 secs. Twice, 8 secs, Three times, 12-15 secs. These presses are kind of right after each other. If you let it sit some period or time (we aren't sure how long) its back to 4 secs again.
Any ideas??
