In/out Band
RFC 2833
In/Out Band is used to define the method of transporting DTMF tones to
use on RTP connections. In-Band are tones that are “heard” by the distant
party, and Out of Band tones are used for signaling.
MD5
RFC 3261
Message-Digest Algorithm 5 - is a widely used Cryptographic hash function
(security) that uses 128 bit hash value.
QoS
RFC 2990
Quality of Service assigns different priorities to different data packets.
Voice, for example, will receive a much higher priority than non-voice
traffic, so it receives the highest priority. Therefore, QoS is used to
prioritize specific packets, such as voice, within a packet-switched network.
However, it does not guarantee voice quality.
T.38
ITU-T T.38
T.38 is the standard for transporting FAX transmissions, between G3 Fax
devices, over an IP Network.
RTP
RFC 1889, 3550
Real-time Transport Protocol provides end-to-end network transport
functions suitable for applications transmitting real-time data, such as
audio, video, or simulation data, over multicast or unicast network servers.
RTP is a standardize protocol for delivering audio and video over the
Internet.
SDP
RFC 2327
Session Description Protocol is purely a protocol that negotiates between
two endpoints to allow them to agree on a media type and format. It is
intended for describing multimedia sessions, and to on a wide range of
networks and networking environments.
SIP V2
RFC 3261
Session Initiated Protocol is an applications layer control (signaling)
protocol that is outlined in the “Internet Official Protocol Standards”
document number RFC 3261.
ToS
RFC 791, 1060, 1122, 1123,
1195, 1247, 1248, 1349,
2474, 3168
The Type of Service octet is part of the Internet Protocol header that
specifies the priority of the attached datagram (message).
DTMF
RFC 4733
Dual Tone Multi-Frequency Tones - also known as touch tones
®
- Defined
protocol for transmission of DTMF tones transmitted over a packet
switching network.
AF Class
RFC 2597
One part of QoS, is Assured Forwarding Classes. This allows the
administrator to divide the IP Packets into one of 12 different Classes. In
the event that the network becomes congested, the packets with the
highest Drop rate will be dropped.
EC
RFC 3246
Expedited Forwarding has the characteristics of low delay, low loss, and
low jitter, making it suitable for Voice, Video and other real-time services.
