Had a call from this number yesterday. It was silent, so I thought I would ring back on the work phone, it said this number is temporarily unavailable.

Just had a phone call from this number but I didn't know it so I didn't answer.. Glad I googled it instead of calling it back, just looked dodgy I guess

Just got one at 1:16pm myself.  I have bad reception at work so didn't catch a word of it.  Have had a few unknown numbers hitting my mobile recently.  Getting a little tired of it.

just got a call as well, answered it but no answer, not going to call back!
this is the second time for me.

the other number was (02) 9016 5617 > when you call that one back don't use mobile as i read it is a scam, but if you use a landline it is always engaged.

I too just got called by this number and missed it, As i thought it was despatch trying to contact me. i rung it and got the same msg  "Currently we are unable to process your call, as this number is temporarily unavailable"If it is a scam, i can/will track it the number down.

Got the call thrice in 24hrs time... didn't tried to call back and thought it might a scam then started googling. which helpful.
