alright -
*79 - 3-1 and 3-2 are set to 500

here's whats weird - and may help. grr
doorphone a - grabs co line 5
doorphone b - off hooks onto co line 10
doorphone c - off hooks onto co line 15.

Program *33, 500 should be set to what? the phone/s I want to ring, or the doorphone's port, when I looked at the old brain's programming it didn't have anything set. if it needs to be blanked, heh, how can I reset it back to default.

now if you say it looks like the doorphone is programmed to do that. what program should I look under.
