I got a call from this number with Caller ID "EVH". I didn't pick up, and no message was left. I've had at least one call with the same Caller ID but a different number, 604-630-9665, same thing happened: I didn't pick up, no message was left.

There's a record on this site for 604-640-9665. When people do pick up there is only silence or the caller hangs up without saying anything.

Since both numbers use the same Caller ID it seems they might be related, and they're in rough sequence, i.e. 604-630-96XX, which suggests somebody has a block of numbers. An office, perhaps.

Neither number got a hit on Canada 411.

this phone number called all the time, never leave a message, they are very annoying.
i do not answer this number because, i suspeck they are scammers, i have no business
with them and i do not answer the phone.  i remember their numbers and just ignore them.

I just got a call from this same number. My wife answered and a person asked for Mr. Rockets. That's close to my last name but not the same.

Sounds like they were going to try and sell something.

This one's going on my block list!
