Communications provider Voiceflex is warning customer to be on the alert for comms fraud and issuing the following alert to all their accounts between Wednesday 9th and Thursday 10th February 2011.
Voiceflex says, “Fraud has been in the telecommunications industry for many years! There are a number of different types of fraud; they ALL have the same result – telephony fraud will cost YOU money and unfortunately it’s on the increase.
The majority of fraud experienced by customers occurs when the local area network is accessed illegally (hacked) and the telephony system reprogrammed by the fraudsters to allow calls to come in over the internet and route out either via ISDN, PSTN or SIP Trunks.
Should your system be compromised in this manner and as an example if you had 4 telephone lines routing fraudulent calls to Cuba over a 5 hour period, the cost to you would result in a bill in excess of £1,000. And since telephony carriers will not insure against fraud, ultimately you are liable for the calls made.
Another type of fraud involves the telephony system being “hacked” and reprogrammed to consistently call an international number equivalent to a 08 or 09 numbers because businesses with 08 and 09 premium numbers make a profit on calls received.
Staff making private calls is the other most common misuse of your telephone system and inevitably results in lost productivity and again in telephony costs; a double whammy.
Voiceflex isn’t responsible for securing your network but we can provide you with the tools to help you minimise your risk if we suspect fraudulent calls are being made from your location.
You will only be informed about the service provided on Voiceflex SIP Trunks. You may well have a prime or alternative carrier for your telephony application. This is not covered by Voiceflex.”
Voiceflex is adopting a process whereby the email address which receives the monthly invoice will be notified if the cost of calls for a given day is 10% more than the same day in the previous week.
e.g. If Thursday 3rd Feb -calls spend is £100.00 and a week later – Thursday 10th Feb call spend is £105 then no e-mail sent (less than a 10% increase).
If call spend on Thursday 10th Feb is £120 (increase is greater than 10% of same day 7 days ago) then an e-mail notification is sent to the primary user informing them that the default setting of 10% has been breached.
The company recommends that users need to check the online portal to identify any unexpected calls, If nothing is unusual then no action is required. If you see unusual calls to international destinations then call your telephony provider.
