I got a call from this number, but no one said anything.

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.

On my display, it showed sialk.ca

I have received way too many calls from this indian accent guy in the past months to my work phone looking for one of my employees here. The # that showed on the caller ID before was different. It was, if i remembered correctly,it's 5155. This is the first time that it uses the (416) 555-7777 #. The guy was rude and when I told him the employee can no longer be reached at this #, he got upset and asked WHY.
On previous occasions, one of my managers answered the phone and told him we don't take message for employees and he got REAL mad and kept calling the line for 20 times.

He said it's legal matter and need to talk to the employee. But...if it's legitimate legal issue, shouldn't you have all those information handy already??

It's so annoying to receive calls like this in a such a daily basis

i get call from this number everyday, sometimes 10 to 15 calls each day but  do not pick it up. can some one tell me where the call is comming from??
