This community has been most helpful with this door entry system we are doing for this customer. We have one last hurdle:
Right now we have the door entry system programmed as one of the buttons on the 7962 phone.
If they need to open the door AND they are using the phone to talk, they must put the caller on hold.
This is unnacceptable to the client.
Is there a way to configure the UC540 so that the door can be opened without putting the call on hold?
