caller said nothing

Today I received a call from this number and could not hear anything, just somebody trying to say something but very far and very unclear. So, I googled the number and found all these comments here. In the meantime the phone rang again and it was my mom in law calling from abroad. I know that she is using a phone card to call abroad. So, this number is probably the number of the phone company that sells these phone cards. So people using these cards could be from anywhere in the world I imagine. Some just  misdial the number and get to you instead of the intended person and some might misuse the card to place a scam call. Just be aware it is somebody from abroad and might not necessarily be a bad person.

I just received two calls from this number. The person sounded like he was far away and he also sounded foreign and I couldn't make out what he was saying.

My employer has been receiving dozens of calls almost daily from this number. My staff is being constanly harrassed by different callers daily. My employee's are reporting they fear for their safety. Each time they call, we request to be placed on the do-not-call-register to no avail. Do not accept these calls. Always fight terrorism anyway you can!

I am from Toronto, Ontario, Canada which is actually the city where the area code is 416. However, as a long time resident of Toronto I know that 555 is NOT A LEGITIMATE 2nd 3 digits! This is spam! For sure! Let me tell you this: When a commercial is made for air/posting around here and they need a fake number they use 416-555-xxxx as the number because NOBODY'S SECOND 3 DIGITS IS 555. So no one will get a spammer call.HOWEVER, this means that this caller is somehow displaying (416) 555-7777 as his/her caller ID while calling from a different number.Furthermore, I saw the 647 number posted above. 647 is the Greater Toronto cell phone area code. So that may be a legitimate number. However, it may not necessarily be the number of the caller who was spamming you.I am dissapointed that some retard is giving a bad rap to the 416 :(

Sick and Tired!
I have been gettting 3 to 4 calls a day from this number. They never leave a message, I am sick of getting these calls. How can I block this number?
I have answered a couple of times and I hang up after he says hello, I can barely understand him because he speaks poor English.

What can a person do?????
