Voip Switch

VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet . If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.

Early providers of voice-over-IP services offered business models and technical solutions that mirrored the architecture of the legacy telephone network. Second-generation providers, such as Skype, have built closed networks for private user bases, offering the benefit of free calls and convenience while potentially charging for access to other communication networks, such as the PSTN. This has limited the freedom of users to mix-and-match third-party hardware and software. Third-generation providers, such as Google Talk, have adopted[1] the concept of federated VoIP�which is a departure from the architecture of the legacy networks. These solutions typically allow dynamic interconnection between users on any two domains on the Internet when a user wishes to place a call.

VoipSwitch system consists of the main package and additional modules extending its functionality. The main package includes the SIP/h323 softswitch, built-in billing system based on SQL, web interfaces both for administrator and for endusers, SIP softphone with embedded voip tunnel client and some other useful tools. The additional modules are optional and can be added to the system at any moment without interrupting current activity.

VoipSwitch is a complete software platform that can serve different purposes and be used in various applications, for example:

  • By Internet Telephony Service Providers as the base system for offering voip services to end-users
  • By wholesale voip termination brokers as the traffic controller
  • By enterprises that want to connect their remote branches
  • As an IP PBX system.

Why Use Voip ?

There are two major reasons to use VOIP :

  • Lower Cost
  • Increased functionality

Lower Cost

In general phone service via VOIP costs less than equivalent service from traditional sources. This is largely a function of traditional phone services either being monopolies or government entities. There are also some cost savings due to using a single network to carry voice and data. This is especially true when users have existing under-utilized network capacity that they can use for VOIP without any additional costs. In the most extreme case, users see VOIP phone calls (even international) as FREE. While there is a cost for their Internet service, using VOIP over this service may not involve any extra charges, so the users view the calls as free.

Increased functionality

VOIP makes easy some things that are difficult to impossible with traditional phone networks.

  • Incoming phone calls are automatically routed to your VOIP phone where ever you plug it into the network. Take your VOIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls.
  • Call center agents using VOIP phones can easily work from anywhere with a good Internet connection.
