Voice over IP VOIP¹ - A Strategic Imperativë for Corporate Growth and Survival
S. Maurer
One of the key issues with all traditional VOIP¹ protocols is the wasted bandwidth used for packet headers. Typically to send a G.723.1 5.6kbps compressed audio path will require 18kbps of bandwidth based on customary sampling rates. The difference between the 5.6kbps and 18kbps is packet headers.
The hybrid switch [PBX plus VOIP¹] lets enterprises leverage legacy equipment and infrastructure. Hybrid PBXs are popular as they let enterprises rip and replace gradually. They accounted for 55% of PBX sales at the end year, bringing in $900 million in revenue in the fourth quarter; the number of lines shipped endure year was up 21% from the year before, according to the Dell'Oro Group.
Single mark of calling: With commercial services such as Vonage, IT¹ is imaginable to connect the VOIP¹ router into the existing central telephone box in the hoapply and have VOIP¹ at every phone already connected. Other services, such as Skype & PeerMe, typically require the use of a computer {316}, so they are limited to single mark of calling, though handsets are instantly available, allowing them to be used without a PC.
Marketing and Sales: Being the digital telephony of pratically non-existent cost or, in the worst hypothesis, with reduction of 70-80% in its costs, IT¹ is very aplicable to a marketing and sales through telephony VOIP¹.
Voice over IP VOIP¹ represents the technology that uses digital packages of data to transmit the voice {849}, in the Internet or Web. When the first belief of using the Internet to do call calls became more or less reality 5 years ago, a collection of enterprises introduced products and softwares that produced poor quality of voice.
Ham Radio operators using radios are able to tune to repeaters with VOIP¹ capabilities and employ DTMF buttons to command the repeater to connect to various other repeaters, thus allowing them to talk to human beings all encircling the world, however powerful their radio.
As the popularity of VOIP¹ grows, and PSTN users switch to VOIP¹ in increasing numbers, governments are becoming more interested in regulating VOIP¹ in a manner alike to legacy PSTN services.
The call enterprises see the writing on the wall. AT&T and Verizon already offer great-business VOIP¹ services. They're upgrading their network backbones with Multiprotocol Label Switching {704}, a path to label different types of IP traffic for prioritization. And they're starting to implement the IP Multimedia Subsystem, a standards-based network architecture that will let them provide and charge for services that enable both wired and wireless devices [like cell phones, PDAs, and laptops] to employ VOIP¹ and the applications that go along with IT¹, including videoconferencing, instant messaging, and presence awareness.
Following the lead of mobile telephone operators {302}, several VOIP¹ carriers are already implementing a technical work-around. The United States Administration had locate a deadline, requiring VOIP¹ carriers to implement E911, however, the deadline is being appealed by distinct of the leading VOIP¹ enterprises.
The challenge that the telephony through Voice over IP faces IT¹ is to give the voice, fax, or video packages {768}, in a safe flow to the user, and she makes this taking the voice or data of the source where IT¹ is then digitalized [converting from analog to digital], compressing [since of the limited bandwidth of the Internet], and sent by the Internet [the action is inverted in the destination side].
Recently British, the telephone enterprise of England, decided to substitute dozens of thousands of conventional telephone public cabines by VOIP¹.
We will imagine that you have your main office in São Paulo Megalopolis and a Branch in Paris or Rio de Janeiro cities. With 2 of those VOIP¹ equipments, one on each side {616}, the PBX of São Paulo can communicate with the PBX of Paris or Rio de Janeiro, free from the bill of the teletelephone enterprise and practically with the same voice quality of the conventional analog telephony.
Mobile phones: Telcos and consumers have invested billions of dollars in mobile phone equipment. In developed countries, mobile phones have achieved nearly complete market penetration, and many human beings are giving up landlines and using mobiles exclusively.
The bandwidth of the Internet is one of the key factors for a design based on Voice over IP well done, and this should be tested locally before any decision.
Using one of those telephones or PBXs to speak with any conventional telephone in any part of the world, with reductions of up to 80% in the tariffs.
