VoIP Telephony is one of the fastest growing telecommunication services in the world. Voice over Internet Protocol (VoIP) is a technology that uses IP-based networks to transmit voice traffic, rather than the traditional circuit-committed protocols of the public-switched telephone network (PSTN). The major advantage of VoIP and Internet telephony is that it avoids the charges imposed by ordinary telephone services, combined with ease of implementation, high quality and rich functionality.
Nergy Telecom is one of the leading players in the telecom market in a number of regions, thus enabling its partners to provide various VoIP services in their home countries. These services can be provided in virtually any country. In order to implement VoIP services, the agent will need to purchase a VoIP gateway or use their own existing one, obtain an Internet connection (Dial-Up, Wireless, Cable, DSL, E1 or T1, ISDN or Frame Relay) and – if he is distributing calling cards with local-access numbers – obtain phone lines (either analogue or digital) from the local telephone company.
How does VoIP Telephony Work?
With the use of a small device the size of an external modem, Nergy Telecom Partners can send voice traffic directly over the Internet to Nergy Telecom’s switch, thus eliminating the cost of callback, toll-free access or local telephone company costs. Nergy Telecom’s switch acts as a gateway and sends calls via its own channels to the destination phone number.

What are the VoIP Applications that are Supported by Nergy Telecom?
The most popular VoIP telephony applications used by Nergy Telecom partners are the following:
Residential and business VoIP services
Cost-saving and reliable communication are the keys to the success of any business co-operating with international partners .Taking into account such needs, Nergy Telecom Partners can provide access to cost-saving international calls for multiple employees of these companies by connecting the 2- or 4-port gateway to an existing company’s PBX. Whenever an employee needs to make an international or national call, he/she simply uses the office phone with the VoIP Direct Dial service. In order to initiate the service the employee will need to dial an internal number, for example 111 and enter a PIN Code and a destination number. If the identification of the user is not required, the PIN Code can be skipped and an employee can dial any number directly.
Alternatively, the VoIP services can be also provided by Partners to home users who want to place cost-saving Internet calls by using IP phones or Softphones.

What is the Difference between the FXS and FXO Gateway?
FXS and FXO are the names of the ports that are used by analogue phone lines and are often associated with a VoIP gateway. Depending upon which gateway type, FXO or FXS, is used there can be a number of applications for individual and business needs.
The FXS gateway allows regular phones, fax and PBX to be connected to a VoIP system (Nergy Telecom network) by plugging phone cables into the FXS ports of the gateway and thus, they can be used for Callshop and Business applications.
The FXO gateway allows PSTN lines and PBX to be connected to a regular phone system by plugging the PSTN lines and PBX into the FXO ports of the gateway and thus, they can be used for calling cards and Business applications as well.
There is a number of different ways to combine FXO and FXS gateways in order to use them for Callshops, calling cards distribution and Business applications at the same time.
