描述 ISDN user-network interface - Data link layer specification ISDN user-network interface layer 3 specification for basic call control Procedures for document facsimile transmission in the general switched telephone network - Corrigendum 1 T.38 is an ITU standard for sending FAX accross IP networks in a real-time mode. FAX messages are sent as UDP or TCP/IP packets. Pulse code modulation (PCM) of voice frequencies Dual rate speech coder for multimedia communications transmitting at 5.3 and 6.3 kbit/s Coding of speech at 8 kbit/s using conjugate-structure algebraic-codeexcited linear-prediction 7 kHz Wideband audio codec operating at 48, 56 and 64 kbit/s. based on Siren codecs and offers lower bit-rate compressions (24 kbit/s or 32 kbit/s) based on ACELP and offers even lower bit-rate compressions (6.6 kbit/s to 23.85 kbit/s) Short for Internet Low Bit Rate Codec .It is designed for narrow band speech and results in apayload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s for 20 ms frames. A lossy audio compression format developed by the IETF, can be adjusted seamlessly between high and low bitrates, that is particularly suitable for interactive real-time applications over the Internet. H.264 is a standard for high-definition video recording, compression, and distribution. The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard are jointly maintained so that they have identical technical contents Data protocols for multimedia conferencing User Datagram Protocol (UDP) Internet Protocol (IP) Internet Control Message Protocol (ICMP) Transfer Control Protocol (TCP) File Transfer Protocol (FTP) Domain Names Implementation and Specification RTP: A Transport Protocol for Real-Time Applications RTP Profile for Audio and Video Conferences with Minimal Control NFS: Network File System Protocol Specification RTP Payload for Redundant Audio Data SDP: Session Description Protocol Uniform Resource Identifiers (URI): Generic Syntax An Architecture for Differentiated Services SIP: Session Initiation Protocol Assured Forwarding PHB Group; An Expedited Forwarding PHB Hypertext Transfer Protocol -- HTTP/1.1 HTTP Authentication: Basic and Digest Access Authentication A DNS RR for specifying the location of services (DNS SRV) URLs for Telephone Calls RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals The SIP INFO method RTP Payload Format for ITU-T Recommendation G.722.1
