Nuisance and fraudulent phone calls

We are starting to receive a number of complaints regarding Nuisance and fraudulent phone calls coming from numbers allocated to Net-Work Internet Ltd (

We are a Telephone Communications Provide regulated by Ofcom and as such have over 1,000,000 numbers allocated to us.

When you receive a nuisance call from a number allocated to us, these calls are not actually coming from us.

These calls are usually being made by unscrupulous businesses that spoof the CLI (Caller Line Identity). This means that the number you see as the calling number, or the number read back to you when you call 1471 is forged. They do this so you cannot trace where the call is coming from. They tend not to use “Number Withheld” as the find that these calls are blocked or not answered.

You can confirm if a number has been spoofed by calling the number that called you back. If you hear a message saying the number is not in service, or you get an unobtainable tone this means the calls made to you were using a forged CLI.

If the call is answered, you should take the case up with the person answering the phone. If you get no joy from them please contact us at with date and time of the call you made. Please also provide the number you called from and to. We will then look into this for you.

We are often asked why we cannot stop these calls. These calls do not originate from our network, most of these calls originate from call centres in India. As the calls do not touch our network we cannot stop them. It might be worth you contacting the communication provider providing you with your line as they may be able to block the number on their network.

Many complainants tell us that they are registered with the Telephone Preference Service. Unfortunately, the people making these calls are usually based abroad and have no respect for UK law.

You might consider reporting the incident to The Information Commissioner’s Office

If the incident is a serious one and you have been a victim of fraud please report the incident to:

It has only just come to our attention that the email2fax service has become very unreliable. This seems to have started 3 months ago, although it is difficult to pinpoint the exact date the problem started due to low usage of this feature.
I have just reviewed the logs relating to this which show the problem being outside our network and therefore outside our control.

The service has only been used/attempted to be used, a hand full of times in the last 6 months. The investment needed to try and fix the service can not be justified based on current usage and projected future usage.

We have therefore reluctantly taken the decision to close the email2fax service with immediate effect.

We apologise for any inconvenience caused.

We will continue to provide our popular fax2email service which is working well.

Problems Experienced this morning 12 June 2015

This morning we experienced communication problems between ourselves and BT. This effected incoming calls from the BT Openreach network.

The problem was caused by routing going through the Level 3 Network (One of the biggest networks in the world).

Here is a plain English explanation as to what happened at Level 3 this morning.

We always evaluate incidents like this and where possible improve our systems to stop the same problem accruing in the future.

As the problem was outside our control it is impossible to guarantee it could not happen again, however we have determined that the risk of it happening again can be reduced  by adding additional routing to and from our network. This work will be undertaken over the next 3 weeks.

We apologise for any inconvenience caused.



New Web Site Under Development

We are currently revamping the Net-Telco web site. The site will be more mobile friendly and have a cleaner look.

The Number management portal is being split off from the main web site.
