I have a 9216 Aastra. I am taking over a new office and the phone has 15 callers of people who have nothing to do with me, is there a way to clear these callers, or do I have to wait for 15 new calls to come in?

The cable from the base unit to the handset may be faulty or not properly inserted,

All incoming calls get a busy signal

Scroll through all Callers, one of them is stuck as "new",

What is your SIM card type ? Call your provider service center to get your PUK

if the phone is an AAstra phone model 9116 (look on the underneith) then hit Options then down arrow (under the viewer) to the indicator message then hit delete and then save
if it is a 9216 or 9316 model then slide the little bar(under the view glass to the right and hit the button under the slide and down arrow to option 4 and hit the 4 button and turn of the indicator. it will work properly imediately and resume as it should..
to prevent this , after you listen to your messages hit the * button twice before you exit your voicemail system

Telephony configuration might necessary...
