We have an intercom at the gates here. In the old situation we had a phone connected to it, via the old Philips PBX. That phone needed 50V or so I am told, and that is why it doesn't work anymore.
So we let the phone at the gate call to a directory number, and made that number a line at the reception phone. Problem is that the old phone sent #0 at the end of the call, to let the intercom at the gates know that the conversation is done. Since our 7961G IP Phones don't send this command, the line stays busy until the timeout has expired.
The workaround for this is to let the receptionist type #0 at the end of the conversation, before laying down the hook. Ofcourse this isn't the nicest way to solve this, so I was wondering if it is possible to let the phone automatically send #0 to the intercom when the call is over?
