The reason you are unable to call back is that each of these callers is actually caller from a real number but they are Primus customers, so their real number actually gets re-routed through one of many Primus main numbers.My father has Primus and whenever he calls me the caller ID shows one of the many Primus numbers, usually I get (416) 646-3601, but I have also seen others.So basically if you signed up with Primus today as your phone provider you too could make calls randomly to people and they would get a Primus # on their call display.It is so frustrating and Primus should not be allowed to mask the caller ID number.

I work for an investment firm and people call from this number constantly trying to get through to the company President.  They say they are from the US Pensions group and have clients that want to invest with us.  When I try to get additional information. like a call back number or their website, they  either hang up on me, or become rude.  They have gotten through to my boss a couple of times and he's said 'not interested', and I've told them as well, 'we're not interested, remove us from your call list'.  They continue to call!

Do they keep notes on who sounded like they answered last time?Why hang up without saying anything?What a waste of time.What is their motivation?Are they somehow making money?Do they get the occasional dummy who gives them money?Or are they insane?I don't understand.

This is seriously annoying, today I got a call from +40555600842 on my cell phone at 11:09, I was asleep, luckily with my ringer on very low, obviously I didn't wake up to answer it, at 11:10 and 11:11 I got calls from a private caller, then an unknown number at 11:12, at 11:14, our friend at (416) 646-3601 called, and then at 11:15, a caller from 662-505-2872, I finally woke up at 11:18 when another private caller called. At that time I looked at my phone and saw all the missed calls, no messages though. How do these people manage to find my phone number, and why do they feel that calling 7 times in 7 minutes is going to get a response?I tried to trace the numbers, the unknowns and privates didn't work out, but the first call was from a caller calling through Romtelecom in Romania, but calling through the provider from outside of the country. I literally don't know any person or have any connection to anything remotely Romanian. The area is Caras-Severin, which includes Transylvania. Perhaps it's Dracula.The next number that came up, the 662 number originated from Mississipi or Memphis, Tennessee. I'm a Tennessee Titans fan, but otherwise I have no link to either of these places either.Finally, of course our favourite caller, the one at 646-3601, called in between.Has anyone received a REAL phone call from any of these numbers?

Phone number is being linked to any local service provider. It is a Skype VOIP number and is untraceable.  Any person with internet access can call via Skype and have this number show up on the call display. Contact your service provider and have this number blocked from calling you. Only solution thus far.
