There is more to communication than just an easy interaction guaranteeing the transfer of messages from one man to another. Nowadays, the ideas, the points of view, the significance of this or that thought ? i.e. messages ? have surely acquired advanced means of transmission, among which VoIP has started on a promising path. The plus with VoIP is that it is going beyond ?just? communication. VoIP shows all the signs of a technology designed for enhancing human interaction. VoIP ensures effortless, high-quality communication by seizing the extraordinary opportunities provided by the complex improvement of Internet mediated contacts. Basically, VoIP services let us make unrestricted, worldwide, long-distance calls at very cheap prices.

Essentially, engaging in PC to phone calls with the assistance of VoIP technology is equal to doing away with long-distance costs for telephone calls you make from your residence or from your workplace. Moreover, the offer does not come alone: truly cheap PC to phone calls are accompanied by an entire set of completely free of charge packages, for which a regular landline demands additional payment ? such packages include call waiting, voice mail, caller identification services and so on. Consequently, PC to phone calls enabled by VoIP services do not accomplish only the great task of flexibility ? since you can make them from practically any place known to have a functional Internet connection ? but also that of significant cost reductions. Additionally, an internet telephony service provider renders possible not only PC to phone calls, but PC to PC and phone to phone calls (VoIP enabled) as well. However, internet telephony does not necessarily imply the use of a telephone ? in the traditional meaning ? so as to be able to talk with someone else. Calls through VoIP can be made as long as both ? or all ? parts potentially involved in the conversation are linked to the Internet and are equipped with a microphone and a pair of earphones.

Also, in the case of PC to phone calls facilitated by an internet telephony service provider (commonly known as an ITSP), you can notice the sound quality is as good as and most often better than what you are used to by your regular landline. The sound quality will not suffer if you engage in a PC to phone call where the number you are calling belongs to a standard telephone line. Whether the PC to phone conversation takes place while at the other end of the call a regular landline number is the receiver or whether the communication is enabled by the use of a specifically designed IP phone, VoIP functions on the basis of a voice signal sent over the Internet in digital packets and translated into voice again at the other end of the line.

Of course, there is even more to VoIP than what we have said until this point. The technology involved in the simplification of VoIP enabled PC to phone services do not use only an Internet connection and some pieces of hardware. Internet telephony features such as call hold, call transfer or call conference generally benefit from the help of enabler protocols, out of which the session initiation protocol ? or SIP ? is the protocol for VoIP and of a number of interactive packages sessions, such as instant messages. Broadly, SIP is designed for generating, controlling, adjusting and ultimately concluding sessions with one or more partakers. Whether you, as a potential beneficiary of VoIP enabled PC to phone calls, opt for the prepaid phone calls or for the postpaid deals an internet telephony service provider can come up with, the role that SIP plays is of the foremost significance, since it primarily guarantees the telephone call is going to actually connect with the called person(s). Even more, if any changes occur during the conversation, SIP will make sure that they are supported throughout the conversation ? such changes may concern features like call hold or enablement of video functions. Therefore, in a PC to phone conversation, you can rest assured for SIP supports a great number of standard telephony attributes and even more than that. So, if you are concerned that a PC to phone call can not keep up with features such as call waiting, call hold, multiple line presences, call queuing, three-way conferencing, automatic call distribution and so on, it is time to leave this concern aside.

Consequently, the advantages of PC to phone services made possible by the internet telephony will take more than the sum of your fingers to count them all. One other benefit stands in the fact that the customer actually has to opportunity to control the sum of money he is willing to spend on his PC to phone conversations, the remarkable opportunity being offered by the prepaid phone calls widely made available. Nowadays, opening and using PC to phone services are commonly prepaid, since it is more convenient for the customer; basically, it means that the beneficiary either purchases a pre-pay calling card or he pays the amount of money in advance by using his credit card. When the sum paid for the VoIP account or for the calling card is reached, the customer needs to take the same steps again. It's the easier way for both the customer and the ITSP, since the risk of scam ? coming from both parties ? is eliminated along with the issues concerning money collecting in the postpaid model. Either way, the cost reductions, the sound quality and the flexibility of VoIP services is worth the minimum of effort you will invest when opting for becoming one of its already numerous beneficiaries.
