Short answer: NOPE.
Longer answer-- The DSHG bundle from Aastra (aka the colored coded spaghetti EHS cables) do not have an RJ9 connection to the phone.
SO, there is nowhere to plug in a Busy Light.
If Customers would like to use the manual switch to turn on the purple light of the Busy Buddy they can. But the red auto light will not work.
Thank you and good night!
