IANA Considerations for IAX: Inter-Asterisk eXchange Version 2
IAX的IANA注意事项：星号间交换版本2
Abstract
摘要
This document establishes the IANA registries for IAX, the Inter-Asterisk eXchange protocol, an application-layer control and media protocol for creating, modifying, and terminating multimedia sessions over Internet Protocol (IP) networks. IAX was developed by the open source community for the Asterisk PBX and is targeted primarily at Voice over Internet Protocol (VoIP) call control, but it can be used with streaming video or any other type of multimedia.
本文件建立了IAX的IANA注册中心、星号间交换协议、应用层控制和媒体协议，用于在Internet协议（IP）网络上创建、修改和终止多媒体会话。IAX是由Asterisk PBX的开源社区开发的，主要针对互联网协议语音（VoIP）呼叫控制，但它可以用于流式视频或任何其他类型的多媒体。

IAX (Inter-Asterisk eXchange) is an "all-in-one" protocol for handling multimedia in IP networks. It combines both control and media services in the same protocol. In addition, IAX uses a single UDP data stream on a static port greatly simplifying Network Address Translation (NAT) gateway traversal, eliminating the need for other protocols to work around NAT, and simplifying network and firewall management. IAX employs a compact encoding that decreases bandwidth usage and is well suited for Internet telephony service. In addition, its open nature permits new payload type additions needed to support additional services.
IAX（Inter Asterisk eXchange）是一种“一体式”协议，用于在IP网络中处理多媒体。它在同一协议中结合了控制和媒体服务。此外，IAX在静态端口上使用单个UDP数据流，大大简化了网络地址转换（NAT）网关的遍历，消除了其他协议围绕NAT工作的需要，并简化了网络和防火墙管理。IAX采用了一种紧凑的编码，可以减少带宽使用，非常适合于Internet电话服务。此外，其开放性允许添加新的有效负载类型，以支持额外的服务。
This document specifies and provides the initial values for the creation of the IAX-related IANA registries as per [RFC5226].
本文件规定并提供了按照[RFC5226]创建IAX相关IANA注册表的初始值。
The IAX protocol, as defined in [RFC5456], defines 15 namespaces that have been registered. These namespaces are described below.
[RFC5456]中定义的IAX协议定义了15个已注册的名称空间。下面介绍这些名称空间。
Each of these namespaces utilizes an 'Expert Review' for extension. Documentation of new values is not mandated as RFCs. The Expert Review should be guided by a few common sense considerations. For example, new values should not be specific to a country, region, organization, or company; they should be well-defined and widely recognized.
每个名称空间都使用“专家评审”进行扩展。新价值的文件记录不是强制要求的RFC。专家审评应以一些常识性考虑为指导。例如，新的价值观不应该特定于一个国家、地区、组织或公司；它们应该得到明确定义和广泛承认。
