Hybrid Key System Product Bulletin

Hybrid Key System Emulation

BluIP brings one of the most powerful features of the on-premise key system PBX to its hosted solution! Now, you can upgrade from a Key System to the latest cloud-based telephony system without having to change the way you use your telephone. With BluIP’s hybrid key system emulation, every user gets their own extension plus all the powerful features you would expect from an enterprise grade phone system including: disaster recovery, mobility, and business app integrations.

The top button on the left of every phone is programmed for your name and extension. The next set of buttons serve as programmable feature keys.

The top-right set of six keys serve as line keys. Imagine you are on a call but want to put the call on hold and pick up that call from another phone in the company. This can easily be done with line keys. Every user will have access to the six line keys. The color LEDs allow you to determine which line keys are available. Green line keys area available. Red line keys are in use. See Figure 1.

Use Case

The telephone illustration shown on the right is an example of a typical medical office. See Figure 2.

The first button from the top is designated as Doctor Joyce’s primary extension and the second button has been programmed as her secondary line extension. When Doctor Joyce is on a call with one of her patients on her primary extension, she can easily put that patient call on hold, and press her secondary extension to call another hospital to request information about the patient. She can easily switch back and forth on the two calls without having to hang up on one.

The third button is programmed as a speed dial to quickly dial the Front Desk and get patient information. Instead of remembering an extension number, a single press of a button connects Doctor Joyce to her staff up front.

Buttons 4 and 5 have been programmed to dial the two Waiting Rooms. The Waiting Rooms extension number can be programmed into every phone in the office so that any staff in the office can go to the nearest phone and call one of the waiting rooms to reach a doctor. The doctor can also page a staff from a telephone from inside one of the waiting rooms and request that they call her from another waiting room.

The last button has been programmed as a DND (Do Not Disturb) button so that the doctor can choose to silence her phone and have all calls immediately go to voicemail if she is in consultation with a patient.
