This is a number from an Optus call centre. You can't ring it back as it won't be answered (outgoing calls only).

Thanks for the warning I had this number call me didnt answer it

I have had multiple calls as well, I think it is a Melbourne based Optus business direct outlet trying to drum up business, the fact u get 4 calls within a ten minute block borders on harassment

Same experience as other commenters. I have added to my 'ignore' list.

Just missed the call so I rang the number back and it is constantly engaged. I save all these telemarketers numbers ( I have listed this as optus con ) so when they ring they are identified and they do not answer.

Also had a call engaged when I tried to return the cal, having read this I wont be answering Im not even an optus customer !

Rude, invasive, definitely claims to be from Optus. Hang up!

I recently add an ap called iblacklist to my iPhone to block callers like this... You need a jailbroken iPhone to add the app, but well worth it.

it appears to be optus

Either number is busy, or ring out! Annoying

got 5 missed calls from it in the space of 10 minutes, tried calling back numerous times, only for it to be either engaged, or ring out (once ringing out about 10sec after it was engaged)

Who keeps calling me from (03) 9221 0238

I forgot to check this site but I was caught a few months ago when I did answer these callers. 4 off them in the one week. They 'were' from Optus but I did not get any new service because of past bad history. Now I know why they were not interested in talking to me about that.

Now I've had 4 missed call in the last 3 days, can't wait till I answer them and have some fun.

Just save this number to your contacts list and mark as 'optus junk, so you can see them for sure when they call, may-be like me you do know some one from the 03 area.

Also have a look on the another site phoneowner.info, same as this one, it has 4 pages about this number!

Keep missing calls from this number and they never have the courtesy of leaving a message.

Just optus sales

...just had a missed call from this no (03) 9221 0238)
some of the previous comments suggest it's bogus
but one suggests it is optus,

any clarification available?

Always getting this number calling me up and thank god when I looked up this number on the net just now and saw this, it's a real help to identify the weirdo's out there trying to offer crap. Great website!
