Constant avaiability through our mobile and smartphones has become a part of our daily routine. Although there are, undoubtably, advantages to this avaiability, for some people this benefit turned into curse, especially as far as unsolicited calls are concerned.
One Company, Innumberable Phone Numbers – Thanks to Phone Number Blocks
Who does not know about the problem of being called by unknown phone numbers? Often the perpetrator is only one call centre disguised behind a broad range of phone numbers. How does that work? On one hand, call centres employ the Voice over IP technology to generate random phone numbers to conceal their true numbers, on the other hand, most call centre request vast blocks of telephone numbers from the network provider.
A phone number block contains at least 10 phone numbers which match each other in their initial digits. The public telephone network offers block numbers containing up to 1000 phone numbers. Some companies with a high affinity to telecommunications maintain block numbers supplying up to 10000 phone numbers to support their telephone systems. Another variant of block numbers refers to the bulk of extension numbers to define a telephone systems substations.
The main advantages of number blocks enables companies the use of Direct Dial Ins, that provides the telephone system’s substation to be avaiable directly from internal and public networks without the need of being relayed manually. As far as the consumer is concerned, he or she will be able to skip the company’s or institution’s swithboard and call the desired colloquist directly through the extension number. Additionally, consumers can recognize the number and attribute it to a certain company or institution.
Call Centres Use a Large Variety of Numbers
De facto most call centres use their number blocks to their own profitable ends. Hence consumer will be targeted by various numbers behind which telemarketers and lottery scams lurk. Most call centre expect their numbers being blocked every now and then. In order to avoid any losses call centres draw on a vast pool of numbers, essentially, thanks to the number blocks provided by the nertwork operator. The more number block a company has at its disposal, the more phone numbers it can employ. Although numbers of nuisance callers are blocked not only by consumer on a regular basis but also by official institution – some only after thousands of complaints – the call centres supply of replacement numbers enables the company to go on as if nothing happened.
