WHAT IS AN IP TELEPHONY SYSTEM?

It is an extensive term used for all the sciences that exchange information of all kinds via the internet. These are phones which help businesses grow. IP telephone systems, also named as, Internet Protocol system, is a replacement to the public switched telephone networks. The information, whether it is voice, fax, or other data, travels through these systems as packets of the internet.

Inferring from the argument, strong internet access is crucial for the proper working of IP telephones. It is used to converge the devices (laptops, mobiles, and telephones). That is all the devices are controlled and run through one elemental device.

Packet and circuit-switched connections

The major difference between the traditional systems and IP is that the latter transfers the data in the form of packets. The former, on the contrary, uses circuit-switched connections. The packets transferred are encoded and are in the form of small distinct packets. These parcels are tagged for their destination and upon reaching there are rearranged into their original order.

Circuit switching is different. It demands a proper end-to-end connection to be established for data transfer. In packet-switched connections, if the internet quality is not good, the data transferred may be disrupted. But in circuit-switched, if the connections are not proper, there is no data transfer at all.

Packet-switched are comparatively newer and, hence, more equipped. The packets are originated from a single source and are directed towards a single destination. Any intermediary route may be used by packets to reach its destination. While such systems are quite useful inside an organization, circuit-switched connections are still widely used. This is because the latter is more reliable.

Summing it up, if a loop is organized consisting of six channels, a packet will move through all channels to reach its destination. The circuits will connect only those channels which imply a direct path from the source to the receiver.

How does IP work?

Like traditional telephones, the IP telephone systems work through sources, pathway connections, and receivers. However, the key difference between these two is that the telephones utilize visible connections or lines to connect the phones. The IP depends on the internet and LAN (local area network) to communicate. These are the same networks used by your laptops or mobile phones to have access to the internet. The system is now referred to as the VoIP system.

The VoIP system

These are the phones that are connected to an Ethernet cable or are usually wireless. These use voice-over technology along with the internet protocol. They are more commonly used as IP phones. Cordless phones, desk phones, and conference phones are common examples. These look like traditional sets but are entirely different.

Working principle

These systems record your analog voice signals and instead of transferring them as sound waves, data packets are used. They are sent into and out of a network and through the internet to the receiver. You can imagine working like that of an MP3 player. Or a wireless connection of two devices. The voice analogs are recorded are changed into digital signals, transferred to the receiver. In the end, they are changed back to voice signals.

IP systems are better for business

Having an IP system means access to a clouded network. Everything required for the setup is in a small box. So there is no hefty hardware required to install the IP systems. Thus begins the tale of how IP telephone systems are changing the business. Since you don’t require proper hardware, the cost four buying it, place of installment and maintenance are minimized.

Another feature of IP systems that have helped it skyrocket is the addition of a new line. With landlines, the insertion of a new phone on the same line is a tedious task. It may take a professional, two to three days, and working at different locations to install a new phone in an existent line. However, with IP, these are as simple as adding a card to the deck. You can do it yourself and no time is required.

IP systems are undoubtedly phones which help businesses. You can take your business number anywhere. Technically, you can carry your office phone with you. You don’t have to share your phone number. Just add a new mobile line on the cloud and take your business around.
