VOIP PSTN And Current Trends in Telephony

Telephony over the Internet has been one of the current technological trends and most recently it has taken several industries by storm. PSTN is short for Public Switched Telephone Network and is a system that works by setting up a circuit between two points. The users can communicate with each other from these two points. These calls are reliant upon the copper wires that are responsible for the transmission of analog data across the dedicated circuits.

For so many service providers, their main purpose has been to serve the users to the best of their capability. The inbound PSTN to VOIP calling has been a source of revenues. More so, there has been a development of software to run through the servers to allow the use of these services by those who have subscribed through the SIP Servers and the PSTN gateway as they make calls. Most if not all landlines worldwide can be easily accessible in this way.

As opposed to PSTN, VOIP uses packet switched telephony. This way, the voice travels to where it is intended to go in several network packets via the Internet. There is a disadvantage with this type of communication in that the Internet was not actually designed for this type of application. The individual network packets that transmit the sound take different paths to a particular destination. For more effective communication, these packets should arrive through a narrow window and they should be chronologically assembled if they are to make sense to the recipient of the message. VOIP has come in handy to employ some schemes to encode and compress the voice packets for increased efficiency and effectiveness of this communication.

There is a notable variation between the features of PSTN and VOIP (according to at least one VOIP guide). PSTN has dedicated call lines while with VOIP, all channels are transmitted via the one and only Internet connection. Compressions in VOIP can only yield in 10kbps headed in a single direction; while for PSTN the speed is 64kbps in one direction. For PSTN, additional features such as call waiting and identification for the caller are available but at a designated extra cost for the user. At the same time, these features are free with VOIP.

For PSTN upgrading can be done with the incorporation of new equipment and the positioning of the lines. With VOIP telecom, all you need to upgrade is the bandwidth or the software if need be. For VOIP, long-distance calls are included in the monthly payments while with PSTN long distance is charged by the minute. Power outages do not affect the functioning of the PSTN landline phones. With VOIP, the phones only function if there is a way to back up the power in case of an outage. Tracing your location from emergency calls with PSTN calls is easy but with VOIP calls it is sometimes impossible to do so.

There are also some free VOIP PSTN calls. Most calls are offered at a friendly and affordable price to enable you to make calls to your family and friends. In the recent past, VOIP has regained its popularity which it had lost some time back. People have found it is a good way of making affordable calls. People also enjoy it more because they can use a VoIP ATA adapter to connect the Internet to analog telephones. This makes voice over IP seem more like a normal phone call.

Experts have begun interfacing VOIP with PSTN and this is made possible by a PSTN gateway. This gateway is the tool that is an intermediary to accessing the switched network for telephony. This gateway has been incorporated into service providers for application software and the providers of Internet services. The result of this has been advancement of the standards that will improve the use of technology and at the same time will enhance the applications for those who use them. There is very high demand for these services and in future, there will be increased access to VOIP and PSTN.

There has been the adoption of a clause of the prioritization scheme and some useful switching mechanisms. This coupled with adequate policy management will allow the presence of a network that is ‘intelligent’. All this linked up with the PSTN gateway ultimately gives an expanded network that can serve the customers and partners in a better and improved way. There will be an improvement on the clarity of the voice, as well as a manageable traffic flow. In a substantial way, these improvements have been known to bring a positive change in the world of business and more so in the business-to-business perspective.

It has been argued that the comparison of VOIP vs. PSTN shows that VOIP holds more water over the latter. The portability of the VOIP phones and their relatively cheap prices has made them a masterpiece. The other advantage it has is the fact that to keep the conversation going, having dedicated copper wiring is not a necessity.

VOIP PSTN is a technological trend in the field of telecommunication that has a warm reception from people due to its speed and reliability at an affordable price.
