How to Set Up Obihai Off-Hook Autodial


Setup the Obihai to auto-dial a number/extension when it goes off-hook. This can be used for door intercom systems, when the button is pressed it can dial an extension on the system (if the door system also needs to be opened then it will require a second Obihai).


Please Note: This has not been tested on all door systems.
