ZONE1511 Helps Companies Avert Thousands of Dollars
of Fraudulent Calls!


Singapore, 20th August 2010 – ZONE1511 launches ZONE BLACKLIST, a unique new service.

It is not uncommon to hear of phone lines being tapped and innocent companies having to pay thousands of dollars worth of fraudulent calls. A check with various telecommunication companies in Singapore shows that the owners of the telephone numbers are liable to pay the bills for such fraudulent calls. Telephone operators here do not have a service that allows their users to block calls to specific destinations to prevent such unauthorised calls. ZONE1511’s Blacklist service is specifically designed to allow its huge base of corporate IDD service users to block out countries where they do not have business dealings. 

ZONE BLACKLIST service - first of its kind in the market, gives its IDD users direct control to block out destinations according to their requirements. They can select to block out calls by country codes, area codes or even a specific telephone number. All these are done conveniently over the internet via ZONE1511’s website ( The so called blacklist can be created, edited or deleted instantaneously.

 “An international American company with a large operation here approached us for a solution to control and prevent calls to unauthorised destinations, or what they deemed as fraudulent calls,” said Ms Selina Chua, Senior Sales Manager.

“They came to us because their existing service provider then could not provide the solution. We listened to their requirements and developed the ZONE BLACKLIST service within 2 weeks”, said Mr Peter Ong, Managing Director, ZONE Telecom Pte Ltd.

 “ZONE BLACKLIST is very useful as we can restrict calls to destinations where we have no business dealings. It gives us greater peace of mind knowing that we are only paying for authorised calls. It’s a fantastic solution for companies to take preventive measures against fraudulent calls” said Mr Seah Chin Tiong, Sales Director of InCall Systems, who has also just taken up the service.
