VoIP phone calls are usually delivered over a carefully-managed network often running Quality of Service (QoS) and the Session Initiation Protocol (SIP).

An Internet T1 (sometimes spelled T-1) is a high speed telecommunication line that can carry 24 digitalized voice channels, or it can carry data at a rate of 1.544 megabits per second.

VoIP over Internet Protocol (IP), or VoIP, is a managed voice and Internet solution for businesses that falls into the industry niche referred to as IP Centrex (a feature-rich hosted analog voice solution), or Hosted Private Branch Exchange (PBX) that provides many features and capabilities that transform business communications beyond what traditional voice and data networks can offer.

The ADSL downstream receiving rate from the Internet usually varies from 1.5 to 9Mbps while the upstream sending rate usually varies from 16 to 640 Kbps.

Ethernet can be used to connect twisted copper pair networks and to connect fiber optic cable networks.

MPLS network is particularly important to businesses running applications that require latency such as VoIP, ERP, SAP, etc.

Ethernet access to the Internet is quickly becomming a popular service. Ethernet, which is usually thought of as the protocol used to connect computers and servers on a local area network (LAN), is now increasingly being used across metropolitan wide area networks (WANS) to connect corporate LANs to the Internet. The advantage of Ethernet Internet Access service is that connection speeds that range from 1 Megabit per Second (Mbps) to 1 Gigabit per Second (Gbps) can be accessed via the same protocol being used on corporate LANs.

POTS local loop speed is increased by up to 50 times when a DSL modem is attached at the customer premise and a Digital Subscriber Line Access Multiplexer (DSLAM) is connected to the local access loop at the local telephone company central office (CO).
