Club Telco

Yes it is ClubTelco. Normally with clubtelco is because your bill is 4 minutes over due.

The reason it hangs up is they have a list of phone numbers for the day (or what ever time period) of people they need to call that day and it continues to make a set amount of calls at once and as soon as one person picks up it is directed to a available phone operator, if none are available it will just hang up.
This is so they get the most out of each call center person and always have the call center person on the phone to some one not having the call center worker wasting time ringing people (saving 10 to 30 second if you pick up) or them calling people that will not pick up.

I do not know the money involved but its highly likely that its just under paying and over working the call center that is in what ever country it is in.

They hangup because the auto dialer is trying to work out if a person answered or a voice mail/answering machine picked up, they haven't configured it very well. How do i know this (dont hate me) i installed it way back when i worked there a few years back :)

This is Club Telco. They always ring and then hang up as soon as you answer it, as they want you to ring them back. I used to, but now I refuse to and I have complained to them about it.

My experience is the same. They hang up as soon as you answer the call, repeatedly. Very frustrating.

Managed to catch half a recorded message, saying something about club telco so Im guessing its them

Constant phone calls from this number, and they just hang up the second I answer

They ring and when you answer they hang up. I am guessing Telemarketer trying to verify phone numbers for later call back.

They ring and don't talk when answer get the sh*t with it.
