1. What is a softswitch?

A softswitch is a software-based device in a telecommunications network, which provides managing of voice, fax, data and video traffic, routing of a call within the network, and can process the signaling for all types of packet protocols. VoIP Softswitches are subdivided into two classes—Class 4 and Class 5 softswitches.

2. What is a Class 4 softswitch?

A Class 4 VoIP softswitch is the kind of VoIP software that is used to transit VoIP traffic between the carriers. The main task of a Class 4 softswitch is to maintain the uninterrupted routing of large volumes of long distance VoIP calls.

3. What is the difference between a softswitch and a switch?

Traditional switch is a piece of hardware equipped with physical switchboards to route the calls. For VoIP, softswitches are used. They are installed on servers and work the same way as traditional switches. VoIP softswitch solutions are rising in popularity and will continue to do so.

4. What is VoIP billing?

VoIP billing is a complete financial accounting solution for VoIP carriers.  It collects, calculates and displays information about telephone calls and other services and generates invoices for the customers. The system also offers complete calls statistics, connection quality reports, financial reports and other vital information.

5. What is H.323?

H.323 is a protocol standard for packet-based multimedia communication. Approved by the International Telecommunication Union in 1996, H.323 promotes consistency in audio, voice and data packet transmission in the VoIP network.

6. What is SIP?

SIP (Session Initiation Protocol) is a protocol for initiating, organizing, and terminating communication sessions in applications of Internet telephony: multimedia conferences, phone connections and user connections with different applications.

7. What is a codec?

A codec is a compression and decompression algorithm, which allows constriction of bandwidth. G.723 and G.729 are the most spread options in VoIP at present times.

8. What is transcoding?

Transcoding is the process of converting media stream from one codec to another. This is usually required when a client’s system doesn’t support the provider’s conversion type, i.e. codec. Real-time conversion of VoIP traffic occurs without a decrease in connection quality of the data stream.

9. What is routing?

Routing is the process of selecting VoIP providers from a list to make a VoIP call. Typically, routing in packet-switching networks is a decision-making process that transmits a packet from a source to a destination via various networking paths. Most routing is based on extracting revenue from each call but advanced platforms allow a wider breadth of options, such as origination-based, priority-based, jurisdictional routing, etc. This provides carriers with much more freedom to set and fulfil their targets.

10. What is LCR?

LCR (Least Costs Routing) is a function that allows users to prioritise routing according to the least price per minute to get the best profit.

11. What is jurisdictional routing?

Jurisdictional routing is designed to accommodate US VoIP Traffic. It is a function which some high-end softswitches provide to carriers. It allows them to automatically regulate prices based on intra-, inter-state and non-jurisdictional origination points.

12. What is a revenue assurance system?

A revenue assurance system increases VoIP providers’ traffic quality and profitability. This software constantly monitors the destination, adapts to and selects efficient routes according to the special rules. The revenue assurance system can automatically lock problematic destinations. It guarantees that pre-set targets for minimal desired level of income is achieved.
