The V1 VoIP Class 4 Softswitch
V1 VoIP provides a high performance Class 4 Softswitch for both carrier and enterprise markets. Our Class 4 Softswitch secures the delivery of VoIP traffic or services over multiple IP networks and includes full component redundancy. It is a highly scalable solution for small or large businesses looking to interconnect their VoIP servers. A class 4 switch is used mainly by large telco providers to interconnect to the worldwide telco networks. For VoIP providers, a Class 4 Softswitch can replicate what a class 4 switch does for land line telephone calls.

What is a Class 4 Switch?
A class 4 switch is a computer device used by the U.S. telephone company to interconnect local exchange carrier offices for long distance calls. More commonly known as a Tandem telephone switch, it connects class 5 switches to a larger network. It is a telephone central office switch used to connect the end offices of telephone service networks together. Class 4 switches can only deal with high-speed digital four-wire connections.

Types of Class 4 Switches
There are two types of connection for a class 4 switch. One is called a sector, or local tandem which is used to interconnect to the traffic between class 5 switches within a local access and transport area (LATA). For example, a call is placed from Seattle to Boston. The calls travels through the class 5 switches and find out that it cannot access the Boston phone number through that network. It then connects to a class 4 switch which allows it to connect to another class 4 switch in Boston. It then again connects to a class 5 switch in the local area the phone number is located to complete the call.

Another type of connection for a class 4 switch is called an access tandem switch. This is when a class 4 switch connects to a long-distance telephone company, also known as an Interexchange carrier (IXCs). Much like a local tandem, the same process is repeated but the call travels overseas through the point of presence (PoP) provided by an IXC. It then gains access to the class 4 switches in other countries and can interconnect to the one it needs to reach.

Benefits of a Class 4 Softswitch:
1. Intelligent Call Routing – Uses sophisticated algorithms to reduce cost, latency, congestion, and improve the overall quality of VoIP calls
2. Easy to use User Interface – Provides a simple user interface for local or remote control management of maintenance, configuration, monitoring resources, software updates, firewall management, etc. Choose between a web based GUI or a command line interface
3. Billing Interface – Overview of services provided including Call Data Records (CDRs)
4. External Routing APIs – Fully control routing through the use of applications with an integrated SVI in the existing infrastructure
5. Security Features – Integrated Firewall, password and user name protection, secure external protocols, and reports of any unauthorized access
