VOIP GATEWAYS OR SAVINGS ON TELEPHONY

 A gateway for IP telephony is a device connected to cheap broadband without contract the communication equipment of an IP network and designed to transmit voice traffic over the network.

Most users are accustomed to office telephone networks based on digital, analog, or hybrid PBX. In recent years, there has been active development of their capabilities, but still, they are not as reliable and profitable as IP telephony. Therefore, many enterprises have already switched to new technologies and began to introduce them into their infrastructure.

In order not to completely change all equipment during the transition to a new communication standard, you need to use a special IP telephony gateway. Thanks to it, the transition will be smooth and will allow preserving the analog telephones that office workers now use.

 

CONNECTION OPTIONS

The VoIP gateway acts as a kind of switch, with the help of which analog telephones, standard public lines, and office automatic telephone exchanges are connected to the IP network. This equipment supports three interfaces, providing reliable interfacing with various telephone line devices. Among them:

·       Analog FXO. Provides connection to a PBX.

·       Analog FXS. One or more telephones are directly connected.

·       Digital ISDN PRI / E1. Serves for direct connection to the PBX or in a gap without the need to reconfigure the network.

Some gateway models have a backup channel. It is necessary in case of problems with data transmission. In such a situation, employees will be able to continue working with the analog telephone line.

The choice of gateway connection depends on a number of factors, such as:

·       Range of tasks to be solved (organization of connecting lines via IP, connection to an IP-telephony operator, etc.);

·       type of free interface on the PBX;

·       Availability of opportunities for routing telephone traffic, etc.

The available ways of connecting and supporting certain LAN configurations "behind the gateway" completely dependent on the network parameters of the devices. The connection can be made directly through the Internet network, through a router, or another LAN switch. The network structures behind the gateway also differ. This can be a direct connection to the VoIP gateway of one / several computers, or indirect - using a switch/router working with a different internal LAN.

Therefore, when choosing equipment, you should clearly define the features of the corporate LAN configuration and the set of the required network functions.

 

 OPERATING PRINCIPLE

The IP telephony subscriber gateway is connected to no contract broadband without landline the PBX with forwarding settings. After the installation of the equipment, all international and long-distance calls will begin to arrive at the VoIP gateway. Despite the technological nuances, the scheme looks quite simple: the call goes from the office worker's phone through the PBX to the VoIP gateway, then through the Internet network to the IP telephony operator, and then directly to the remote subscriber.

Such a system fully justifies itself with more favorable tariffs, therefore, the company's expenses for telephone communication will decrease by an order of magnitude compared to using the services of ordinary wire line operators.

 

DIFFERENCES FROM SIP ADAPTER

Buying a VoIP gateway is currently the easiest way to integrate IP telephony into corporate networks - due to a huge range of models, manufacturability, wide network capabilities, and low cost. A voice gateway for IP telephony is an external device that connects to the PBX and performs the function of forwarding telephone traffic to the IP network. Among its key advantages over SIP adapters, it should be noted:

·       The ability to work with equipment of any brand (LG, Panasonic, etc.);

·       lower cost in comparison with expansion cards;

·       minimal costs for installation, configuration, and maintenance;

·       ample opportunities for upgrading VoIP gateways (adding additional channels will not require significant expenses);

·       Use of advanced technical solutions by manufacturers to ensure compatibility with other brands of VoIP equipment.

Today, there are profitable solutions for upgrading the communication system no contract broadband uk for companies with branches in different cities. They allow you to complete all work in the shortest possible time and at the most affordable cost. In addition, access to unique services such as a unified dial plan is opened. With its help, employees from different departments of the organization will be able to quickly exchange information with each other using short phone numbers.

Modern equipment often has additional capabilities, in addition to the transmission of voice traffic: in particular, several ports (WAN - for working with the Internet network, LAN - for connecting to an internal LAN) and technological routing functions. Thus, a VoIP gateway can simultaneously be used to redirect telephone traffic and provide access to the Internet.

Manufacturers offer a large selection of equipment for corporate users, among which there is always a suitable model. It is only necessary to determine the range of tasks to be solved. On the modern market, both the simplest cheap analog IP telephony gateways (FXS and FXO) and multichannel analog / digital models are presented. They differ not only in the list of provided functions but also in size. So, the first in size can be no more than a computer mouse and serve to connect only one telephone set. The latter is rather bulky equipment, mounted in a 19-inch rack and used to connect dozens of telephones at the same time.

 

Features of the system organization

The VoIP gateway interface can be digital or analog. The latter is used if the enterprise has a mini-automatic telephone exchange, an analog telephone line, and standard telephones. The digital interface (ISDN PRI or E1 / T1) is a more technologically advanced option, providing data transfer at a speed of 64/2048 kbps.

Many users prefer to purchase those gateway models that have an additional connector that allows you to use a backup analog line if necessary.

The VoIP gateway is connected to a free port of a PBX, external city line, or internal office line. In the process of setting up the equipment, the traffic transmission route is prescribed. Thus, some calls will go directly through the PABX, while others will go through the gateway and the IP network.

Equipment with 1-16 channels is used depending on the needs of a particular enterprise and the volume of expected traffic. Devices with a large number of channels are also available. Their number is selected in accordance with the number of free PBX lines.

 

MAIN ADVANTAGES

The main advantage of VoIP gateways is the support for a large number of routing protocols (NAT, Bridge, DHCP, VPN, etc.). Connecting a computer to a LAN port provides the user with access to the Internet.

Proposals of IP-telephony operators are aimed at reducing the cost of corporate communications cheap broadband plans no contract with nonresident and foreign partners/clients, as well as paying for public telephony. Installing an SM-gateway for IP-telephony is much more profitable in comparison with the possibilities provided by expansion cards of a mini-PBX. In the list of its main advantages:

·       uninterrupted work with devices of any manufacturer;

·       lower cost of communication;

·       Simple and quick setting of the equipment.
