Operating IP Telephony

WHAT ARE THE DIFFERENCES BETWEEN IP AND ANALOG TELEPHONY?

Analog telephony is a means of communicating via telephone in a traditional way that is voice transmission via telephone lines. The caller and the receiver come in contact via a telephone link which is exclusive to them throughout their exchange.

On the other hand, IP telephony (Internet Protocol telephony), is a digital technology, that is, it is a communication system that uses the telecommunications protocol set up for the web. In fact, the voice is subjected to digitization and then sent as a packet, like any other internet data. With Voice over Internet Protocol, the voice is transformed into a digital signal and this same signal is transmitted over the Internet or via an internal network.

IMPROVE YOUR FLEXIBILITY WITH VOICE OVER IP

If IP telephony seems to be taking over from analog telephony, it is because it has many obvious advantages. Particularly, because it operates on the association of a user with a station and not with a line, it allows one to be able to retain ones telephone number, even in cases of long-term travel, or change of location, of office, etc.
In the case of a company benefiting from IP telephony, the latter wants to equally be interested in terms of its management because it presents a simplicity that the analog telephony does not have. Indeed, with IP telephony, there is no longer any computer data on one side and voice data on the other; they are all transmitted by the same means, which results into a considerable saving of time and a better productivity for the company.
Finally, with IP telephony, any evolution is simple to achieve, you can set up additional telephones or stuck up the network as you wish.

REDUCE YOUR COMMUNICATION COSTS

In addition to the obvious progress that voice over IP can bring in terms of telephone roaming, it also comes with other financial advantages. Firstly, it represents a big interest in the cost of the installation because if one already has an Internet network, the IP communications can pass through it, and in this manner, there won’t be any wiring or installation costs.

IP telephony also represents a financial gain in terms of the cost of communication. For example, in the business environment, installing a private network to link different sites allows totally free calls between them. And for outgoing calls, the cost is much lesser than with analog telephony, especially if these are long distance calls.

OBVIOUS INTEREST IN BANDWIDTH CONSUMPTION

IP telephony does not require a lot of bandwidth, even in the configuration where several sites are interconnected, and as such, the bill for such stream is reduced. In the case of a G729 codec switchover for normal audio quality, the bandwidth consumption will be approximately 30 Kbps IP, and for a higher quality, the consumption will be at 90 Kbps IP.
