I got a call today from this number, it has the pause before they speak, obviously it's telemarketing. blocked this number.

I got a missed call from them today - won't be calling them back thanks to all your comments :)

Telemarketers

I got a call and they hung up when I answered.

Spam

hungup when i answered

Two calls from them today, I missed the first one - answered the second. Apparently they're called CNS and were asking whether I had any insurance policies. I asked to be removed from their database and got a snide 'that's what I expected from you' before a rote speech on how my number will now be removed.

not sure what source it's from

I think it is a telemarketer. I missed the call but no message was left.
