Business VoIP

VoIP (Voice over Internet Protocol) or IP-telephony is voice communication over the Internet (in contrast to traditional telephone communication, which occurs via telephone lines or a mobile GSM / 3G network).

Voice and video communication through computer networks has become popular worldwide since the beginning of the XXI century and is currently widely used by both private users and the corporate sector. The use of IP-telephony systems allows telecom operators to significantly reduce the cost of calls (especially international) and integrate telephony with Internet services and provide intelligent services.

At the moment, the main purpose of IP-telephony is cheap or free long-distance and international calls. To make these calls you need to use the services of one of the providers of IP-telephony and you can make calls from a computer, IP-phone or a regular phone.

However, the main benefit of VoIP for business is the ability to build more efficient corporate communications systems with various voice services. The effectiveness of such systems (compared to traditional) is as follows:

– simpler and cheaper implementation (because VoIP systems are built on the basis of an existing intranet network);
– free voice communication within the company (even with a geographically distributed business structure);
– the ability to access all communication capabilities at home and on business trips (via the Internet);
– the ability to integrate voice services in business applications and business processes;
– advanced features for recording conversations and statistics.

IP-PBX and unified communications systems are used to implement corporate VoIP communication systems.

Work VoIP with Advanced QoS Features

Voice over IP (VoIP) is now ubiquitous. Today, the question for companies of any size is not whether it is worth switching to VoIP, but when is it better to do it. Most importantly, the widespread adoption of VoIP improves the quality of service (QoS). Companies that have delayed their transition due to their previous reputation for VoIP technology due to poor voice quality can no longer worry that important transactions (such as negotiations with customers) will be complicated due to poor quality.

Modern solutions with improved QoS are able to provide professional quality and a positive impression of the company.

Public Internet telephones use the network to make telephone connections, which is mainly useful to consumers. Most companies use IP-telephony inside their own private networks, as this allows for a higher level of security and quality. Using their own networks, corporations have more opportunities to control the quality of voice transmission, which is not worse, and maybe even better than a conventional telephone system.

Internet Protocol (IP), available in almost every corner of the globe, is increasingly seen as more than just a means of transferring data – a tool that simplifies and streamlines the solution to many business problems. The most striking example is telephony, which uses Voice over IP (VoIP) technology.

IP-telephony is becoming increasingly popular, both in the corporate environment and in the consumer sphere. In addition, VoIP is also the basis for building more complex applications that work on the principle of unified communications. Such applications can dramatically change the business processes of any company.
