21 Mar, 2016 – Let me tell you about terminators. No, not the “Schwarzenegger” terminators with machine guns and a smoking cigar stuck between teeth. Unknown terminators of the developing world, who make it possible for you to call cheap via Viber, Skype and roaming.
The phenomenon of termination appeared long before the messengers and the IT-startup boom. This is a set of technologies and actions to maintain Voice over Internet (VoIP-call). Accordingly, the terminator is a person, engaged in the delivery of a call to the end user.
Despite the fact that the VoIP-telephony was followed by the termination, this phenomenon is well established in the mobile communication daily practice: the so-called GSM termination, which delivers calls bypassing the roaming by operators directly to the subscriber using VoIP-technologies.
How It Begins.
Late at night, gridlocked on Route 101, you remember the happy times of the college and decide to dial a friend who has been downshifting in India for a year. You dial his number and count dial tones.
Meantime, the call goes to the base station, for example, AT&T, it is transmitted via a GSM-transit company, and the call is forwarded to Orange in London. The operator calls all over Europe to the Middle East. Etisalat headquartered in the UAE takes a call, funneling it through the GSM-networks in Iran, Pakistan, and finally, the call comes to Airtel in India, where your surprised and suntanned friend, meditating in the morning yoga in an ashram, picks up a receiver.
“Hey, how you doin’? Let’s have a quick word, the communication’s dear!”
No wonder! After all, the cost of one minute of your conversation includes transit services provided by each of GSM-operators, who led the call to India. Therefore, in order to save money and provide customers with attractive international tariffs, the operators use VoIP GSM-termination services.
Using this pattern, you do not hear dial tones after number input, only silence. After AT&T, your call goes to a go-between (originator), which transforms it in the VoIP-format and leads to India over the Internet. A local terminator receives it and converts it using VoIP GSM gateways back to the GSM-signal.
As a result, the call is made without go-betweens and charged at intranet rates of AT&T and Airtel, which is, on average, 8 times lower than the roaming.
Of course, this format will only satisfy the operators of outgoing calls (in this case AT&T), but not Airtel or Orange. Accordingly, each operator in his own county tries to fight terminatorsby finding their equipment (VoIP GSM gateways) or blocking SIM-cards they make calls from.
However, supply creates its own demand. Despite the fact that the VoIP GSM termination is banned at the legislative level in the US, in most of the countries. This market is in a gray area, with the silent struggle underway and terminators continuing to avoid blocking.
On average, every day, about 50,000 minutes of traffic (calls) are terminated in each country. This means that terminators’ VoIP GSM gateways process over 16,000 calls a day. To keep track of this flow, the GSM-operators develop special AntiFraud systems that block phone numbers that make a suspiciously large number of calls, with operators investing millions of dollars to create these programs.
As a counteraction, GSM-terminators use services to disguise their SIM-cards, for example, GoAntiFraud, which simulates a human behavior and allows handling hundreds of SIM-cards. However, that’s another story.
The next time you hear the silence on your phone instead of dial tones – rest assured: the terminator handles your call.
