Posted By: KP On March 5, 2010 Under Internet, Mobile Tricks, Tips and Tricks Categories

Recently a movie named Karthik calling Karthik got released in India, I don’t know what is the story in the movie but the thing what we can understand from the title itself is possible in the real world. The movie is really nice my friends told me but let’s think little different and see how “Karthik Calling Karthik” in real.

Yes, it is possible to call someone from his cell phone number or sms him from his number. Such things are possible because of some loopholes in VOIP.

VOIP is Voice over internet protocol. In this technology one can do telephony using internet protocol. The technology is not so recent. Many companies came out for providing VOIP phone calls at a cheap rate.

See what wikipedia has to say about VOIP

Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.

Internet telephony refers to communications services — voice, facsimile, and/or voice-messaging applications — that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end

But some of the companies left loop holes (bugs) in their software system. One of the bug is calling self number. If a VOIP service is having the bug you can call any number from the number itself. Also same thing can be happen with sending sms.

It can be used to mask a number. In this one can call/sms someone from anyone’s number. VOIP bugs can be used to hide a number.

So when next someone calls you from your number don’t be shocked !
