ial costs and creating an underutilized investment; transmit data at very low rates and resolutions [link widoczny dla zalogowanych], making them poorly suited for delivering high-fidelity audio, entertainment-quality video, or other rich multimedia content; use dedicated circuits for each call, which allot fixed bandwidth throughout the call’s duration [link widoczny dla zalogowanych], whether or not voice is actually being transmitted; cannot be leveraged to provide new or differentiated services or functions, such as video communication, that the network was not originally designed to accommodate.Advantages of VoIP TechnologyVoIP uses packet-switched networks to carry non-real-time data using much less bandwidth. The advantages of such networks are flexibility, efficiency, and scalability.Flexibility: networks can be built in a variety of configurations to suit the number of users, client/server application requirements, and desired bandwidth availability.Efficiency: bandwidth is consumed only when needed; service providers can converge their traditionally separate voice and data networks [link widoczny dla zalogowanych], and carry voice, video, fax, and data traffic over the same network; many terminals can share the same connection to the network and as a result, significantly more traffic can be transmitted over a packet-switched network than over a circui
