IP telephony, also known as internet phone service helps companies that make so many long-distance calls. In IP calls, the customer only pays for calls to the online gateway and company intranet. Therefore, calls are charged at local tariffs rather than long-distance charges.
IP telephony uses IP networks like the internet or another packet switched network to route the calls and provide an economical alternative to standard PSTN phones. With IP telephone, there are 3 kinds of connections namely computer to computer, telephone to telephone, and telephone to computer.
IP Yealink Phones are sophisticated IT & telephone systems that allow wired, wireless, audio as well video communication through the use of IP (internet protocol) networks. In addition, it's possible to extend all the components of IP telephones easily, as IP telephony uses one infrastructure to transfer voice and data. After the basic set up of the IP telephony is completed, switches and control systems with in-line power supply are activated. Then the IP phones get connected to the telephone network, allowing users to make calls. At times, the authorization of callers and numbering plan, as well as set up of voice gateways is done remotely by an administrator through a web browser.
Here are some advantages of IP telephony
Cost-effective--this is the biggest advantage of IP phones. With this technology, users can make long-distance calls at very low prices. It saves a lot of the money used to pay traditional telephone bills and such savings can be huge, when large organizations with a very high number of calls are considered.
Improved voice quality--with constant improvements in Voip phones, the IP phone's voice quality has improved immensely. Not too long ago, IP telephone was widely derided for long delays in transmission and poor voice quality. However, these problems are now a thing of the past. These days, the voice quality of IP telephones is comparable to that provided by rivals like traditional phone systems and PSTN.
Scalable--IP telephony is software-oriented, making it scalable and allowing it to integrate other applications and services too. Adding a new telephone to an already running IP telephone system doesn't require another new line and may be directly integrated in the system in the existing infrastructure.
Lower initial investment--installing a new IP phone system requires significantly less investment than the traditional PSTN system. These savings are in terms of money and time, with the installation of new IP telephones in the existing infrastructure being easier and cheaper. Since it is software-based, the maintenance fees are relatively low and issues can easily be detected and solved.
