Nowadays, VoIP became one of the hottest technologies following up on the explosion of high speed Internet access. PC-to-PC calls, ATA phones, IP phones the existence of VoIP had changed how people think about long distance calling plan. As predicted by some of those experts, VoIP might be the technology that kills off the traditional telephones.
What is VoIP?
If you never heard of VoIP, be equipped for a radical change on current telephony systems and long distance calling plans.
Voice over Internet Protocol, or in short, VoIP, is a simple method that takes ordinary analog audio signals and transform it into digital form and traverse in distance through the Internet. Several ways are used for VoIP calls: Analog Telephone Adaptors (ATA), IP phones, and PC-to-PC calls are some of the common ones. While ATA and IP phones will cost you a certain amount on the initial setup and monthly costs; PC-to-PC calls are absolutely free for any distance calls.
The impact of VoIP technology is huge. With VoIP, you can simply enjoy much cheaper phone calls by utilizing your existing PC set up and data networks. For those of you who are already paying a monthly fee for an Internet connection, this means that you can use that same connection to place free long distance phone calls. This process works by using already available VoIP software to make phone calls over the Internet, essentially circumventing phone companies and their service charges.
Besides, VoIP gives a greater flexibility to business travelers. Make VoIP calls from anywhere with Internet connections thru your laptop. With VoIP, you can also enjoy enhanced calling features such as calls forwarding, caller ids, call blockings and voicemail calls function.
How VoIP works?
We already knew when making VoIP calls, callers voice in analog form are collected; transformed into digital form; transmitted through Internet; and transformed again into analog voice for the listeners to listen.
However, how does the digital voice signal travel? Unlike conventional phone system that relies on circuit switching; voice signals in VoIP calls are transfer through packet-switching.
Packet-switching is the same method that you use when you view a website. For example, as you read this website, your PC does not maintain constant connection to the website. Instead, connections are only made to send and receive information on an as needed basis. It works the same for VoIP calls as this system allows the transfer of information over the Internet to work so quickly. While circuit switching (conventional telephone calls) maintains a constant and open connection; packet-switching builds a connections that is just enough for sending/receiving bits of data in the VoIP conversations.
By utilizing this special way of data sending, VoIP calls can be done with very little data transmission. This in turn allows voice signals to be sent on the least congested lines and thus a cheaper calling plans.
Drawbacks on VoIP calls
While most analysts consider it will be at least a decade before companies and telephone providers make the full switch to VoIP, the hidden power for the technology’s applications nowadays are very impressive.
Not to mention the emergency call issue on VoIP calls; there are quite a few VoIPs drawbacks that need to be solved in order to have VoIP calls replace our conventional telephones. The power problem of VoIP phones, the security of the VoIP calls, as well as the compatible-ability of VoIP phones with other electronics appliances are some of the major problems that need to be solved.
Bottom line
Undeniable, VoIP is now a very powerful communication way that you cant close the eyes to. To replace the traditional telephone system or not, VoIP service is here to hang about. Millions in United States are using VoIP calls nowadays and the numbers seem growing rapidly. With the savings and flexibility that the technology already offers, and new advances just ahead on the horizon, we can expect those numbers will only increase in the future.
