My Church keeps receiving calls from this telephone number. They never leave any messages. I tried calling the number back...adding the *67 prefix.  Someone answered the phone "Hello". Not exactly how a legit business answers their phones.

Caller ID says "TELCO EXPERTS".

For the record, I maintain the telephone system at the Church, and, we're not looking to change hardware or providers.

I was sitting in the Church office when they called again...2x no less!

Again, we are NOT interested in a new telephone system  or switching to an IP based service (hosted or otherwise).

They will not see your response here, and if they do they will not know who you are. Consider getting a call blocking device (or app for your cell phone)-they're available online and start around $45. http://800notes.com/nb/search?q=call+blockers

I think that I'm "venting" more than anything else with this particular listing. This is a landline situation rather than cellular. The system has an auto attendant, but, I've seen this caller transfer to non-default extensions. This means that someone is pushing buttons, and,  not leaving messsges.

The next time I see an incoming call from this organization, I'm seriously considering answering the call, telling them flat out that we are not interested in any changes to our phone equipment/service and to stop calling us.

I understand and hope your situation gets better!
