Experienced VoIP Coders, Consultants for Hire in Ukraine

VoIP stands for Voice Over Internet Protocol, or in more common terms phone service over the Internet. VoIP is available in a wide range of services. Some free VoIP services require all parties to be at their computers to make or receive calls while others let you call from a cell phone to any other phone. You can get phone service delivered through your Internet connection instead of from your local phone company if you have a broadband Internet connection, plus a traditional phone and an adapter, a VoIP-enabled phone, or VoIP software on your computer. VoIP and unified communications allow reducing the phone charges, getting a single network for voice and data, accessing your phone system’s features anywhere you have a broadband connection. The function of turning analog phone signals into digital ones that can be sent over the Internet can either be included into the phone itself or in a separate box like an ATA, but it’s also possible to directly connect to another VOIP user. There are two main reasons to use VOIP – lower cost and increased functionality. Skype, eVoice, Vonage are examples of VoIP providers.
