I called back number (03) 8345 1164 rang 5 times then goes to busy tone.

I got a missed call from 2 numbers. First was (03) 8345 0171 and then from (03) 8345 1164.

Both times they called i was holding my phone. It didn't even ring it just said 'Missed call from..." and then i got a text message saying 'call 159 to receive message...'.

I'm with Optus and i have the message options but i never use it.

I worked out that the phones numbers are from Victoria, Australia...so i assume it's from optus as i've had calls from them before.

Funny enough i had a call last week from Optus from (03) 9982 8878 asking me if i use the functions that Optus provide (aka phone messaging, internally calls, etc) but i said no.

Dunno if this was them again though?
