SDP service delivery platform (SDP)

A voicemail system (also known as voice message or voice bank) is a computer-based system that allows users and subscribers to exchange personal voice messages; to select and deliver voice information; and to process transactions relating to individuals, organizations, products, and services, using an ordinary phone. Voicemail is a digitally recorded message. When you dial someone and they aren't there, you record into a digital mailbox a digitally stored voice message to be retrieved by the owner of the mailbox. While voicemail functionality has advanced in the digital age, all systems are similar. Adding unified communications, or UC, to the mix can take voicemail even further.

In older analog systems, listening to messages was sequential. Messages are stored on a system until they are retrieved -- provided the mailbox isn't full. However, analog voicemail systems are essentially basic recorders with limited features. The digitization of voicemail systems offers greater features as packets can hold any information that can be digitally transmitted.

SDP service delivery platform (SDP)

A service delivery platform (SDP) is a platform that provides a structure for service delivery, including controls for service sessions and protocols for service use. This term is common within the telecommunications industry. It can be vital for services that have to bridge multiple platforms or technologies. However, a service delivery platform tends to be designed for a particular delivery in a single telecommunications format. SDP is a foundation for the creation, deployment, provision, control, charging, and management of telecommunication services provided to the end users. The SDPs represent the programming interface enabling programming of the underlying network capabilities and therefore are primarily based in the usage of information technologies (ITs). SDP may apply to many technologies including VoIP, IPTV, HSD (high speed data), Mobile Telephony, Online Gaming, etc.
