| Entry | Description | | Asterisk | open source VoIP telephone system software | | ATA | Analogue Telephone Adaptor for connecting a standard analogue telephone to be used with VoIP | | CODEC | Coder/Decoder | | DHCP | Dynamic Host Configuration Protocol. Protocol for the automatic assignment of IP Numbers for computers within a LAN | | ENUM | Elephone NUmber Mapping - Protocol used for connecting resource from the telecommunication and internet networks with one another | | G.711 | ITU Audio Codec without compression, with PCM and good sound quality. Requires 64 Kbit/s bandwidth.
International: G.711.A, US: G.711.U | | G.729 | ITU Audio Codec with CS-ACELP compression. Requires 8 kbit/s bandwidth | | Gateway, gw | A gateway connects unlike network systems to one another and allows for communication between the various networks. | | H.323 | ITU Standard for transmitting audio/video conferencing with LAND/Internet | | IAX | Alternative protocol to SIP and H.323 | | IP | Internet protocol (RFC 791 and 1060) | | ITU | International Telecommunication Union | | LAN | Local Area Network | | RTP | Real-Time Transport Protocol | | PCM | Pulse Code Modulation. e.g. for an audio CD (with 44,1 kHz, 16 bit, 2 channels), for DVD (normally 48 kHz, up to 8 channels,up to 6 Mbit/s) and used with G.711 | | PSTN | Public Switch Telephone Network = standard (classic), fixed-line telephone network | | SER | SIP Express Router | | SIP | Session Initiation Protocol, IETF-Standard (RFC 2543) | | STUN | Simple Traversal of UDP over NAT. Used to locate open UDP ports can be used to allow SIP on a NAT-Router | | TCP/IP | Transmission Control Protocol / Internet Protocol (RFC 793). Most common network standard used throughout internet, intranet and LAN. TCP (Transport Layer, corrects transfer errors) and IP (Network Layer, fragmentation/addressing/data transfer). See also UDP | | UDP | User Datagram Protocol (RFC 768). Transmission protocol used in the internet and in LAN (intranet). Built on IP (like TCP/IP) but does not carry out any error correction (e.g. for real time Voice transmission, see RTP) | | VoIP | Voice over IP. Voice transmission in packages over IP Networks | | VPN | Virtual Private Network |
