Can I use a Busy Beacon with my Mitel 5330 IP phone?

MAYBE...?

There are two types of this phone. The ones with the wireless headset attached to the side are not able to connect with a Busy Beacon (see photo below).

If your Customer has a Mitel 5330IP with an attached headset then they cannot use a Busy Beacon(DISCONTINUED) . Sorry!

Any other model of the Mitel 5330IP should be just fine!

This is also true of the BUSY BUDDY light.
