Is someone trying to hack my phone or something?

I've had the following calls:

14:46 04-07-2012 12013155683151
14:37 04-07-2012 19013155683151
14:28 04-07-2012 13013155683151
14:19 04-07-2012 14013155683151
14:09 04-07-2012 1013155683151

Picked up the first two (completely dead line) and ignored the rest but it's getting irritating.

Is there anything I can do to stop it?

Cheers.

Don't worry, your phone is completely safe. Occasionally some carriers can pass a malformed caller ID to us, which causes it to show up in the format below.

You can stop nuisance callers by adding call barring on to your account. It's £3 per month, and can be added here https://www.voipfone.co.uk/account.php#builder-callbar

I hope this helps

Thanks for the very quick reply but I'm really not looking to spend any money right now, was kind of after a free solution.

It's every couple of minutes now, I've had more calls since posting, each with a different prefix.

By malformed do you mean erroneous or purposely malicious?

Is there any way to block this because I'm going to end up having to unplug the phone.

They're all coming from 176.74.218.8.

Can you possibly email us direct at support@voipfone.co.uk from your registered email address please?
We can then take a look at the call records and see whats going on.

I've found the feature in my handset that allows me to reject (sent to VM) calls on phone number or SIP URL so I've managed to use this to block their IP address but I'll email over the details anyway.

Many thanks.

Okay great, thank you.
