VoIP-communication is becoming increasingly popular when organizing office telephony. It provides low-cost communication services and high quality of a voice signal. Using the VoIP GSM gateway, the system can handle the huge flow of information and convert it into digital files as well as transmit them without distortion over long distances via the Internet. In order to organize VoIP-telephony, it is important to purchase a high quality equipment to convert signals quickly and smoothly.
Devices to broadcast phone signals from the IP network to GSM and vice versa is a GSM IP gateway. It is compatible with analog equipment and VoIP-system and serves as a link between them during data transfer. A call going to VoIP GSM gateway gets back, interacting with the PBX, as the signal is transferred to an IP number and extension dialing is performed, and as a result, the call is made. The device transmits the digital voice packages using standardized communication SIP and RTP protocols.
The GSM IP gateway is indispensable when establishing low-cost line for international or long distance communication. You can reduce costs by charging calls at local rates, bypassing roaming. Initially, establishing such a network requires VoIP-telephony providing digital signals, which can already transmit voice in the GSM-network using VoIP GSM gateways.
The obvious benefits of installing VoIP GSM gateways is that you save money when the operator calls the overseas customer base. Using VoIP, you can save more than 60% on communication. In addition, many gateways are equipped with a Call Back feature to dial office phones for free.
There are single-channel and multi-channel VoIP GSM gateways. The first ones are installed instead of landlines, for example, at home, or in a warehouse, when there is little load on the network. With a large flow of calls, like in call-centers, it is better off using the 8, 16 and 32-channel equipment to simultaneously support a large flow of calls.
The principle of the multi-channel gateway operation is that several SIM-cards are loaded in a network simultaneously. Judge for yourself: one line cannot handle 5 or more calls without losing the quality of phone calls other office subscribers make. Multi-channel gateways can be used for heavy load when the hotline phones are required for a certain period. Therefore, under these conditions, you should choose multi-channel gateways that to make mass mailings about promotions and other proposals for customers.
Multi-channel VoIP GSM gateways can be grouped according to mobile operators, which makes it possible to call within the network and choose a cheaper operator. Some brands of gateways, for example, Cisco, are equipped with the minute counter for SIM-packages that allows you to choose the most economical tariffs for calls.
The GSM IP gateway can be set up for any communication that customers require. Using the software, you can install the equipment to send and receive SMS-messages. Such manipulations are required when working with customers of service centers, shops and service sector, where impersonalized contacts with customers are required.
For these reasons, many system integrators, programmers and business people buy VoIP GSM gateways because they allow saving and making money at the same time. Based on a simple calculation, duration of calls by a call-center employee is about 5 hours a day. Investments in VoIP GSM gateways will pay off in 2 months, as they can save communication costs 5 times. It means that the head can afford to make calls to 5 operators for the same amount per employee.
However, there are also pitfalls. For any equipment, VoIP provides relevant software that is worth paying attention to. You should spend a certain amount to install and connect hardware as well as configure it. It will be quite problematic to do it independently. Therefore, when installing the gateways, you should use the operating software package, such as GoAntiFraud.
