英语翻译
The selection of an egress gateway for a telephony call,traversing an IP network towards an ultimate destination in the PSTN,is driven in large part by the policies of the various parties along the path,and by the relationships established between these parties.As such,a global directory of egress gateways in which users look up destination phone numbers is not a feasible solution.Rather,information about the availability of egress gateways is exchanged between providers,and subject to policy,made available locally and then propagated to other providers in other ITADs,thus creating routes towards these egress gateways.This would allow each provider to create its own database of reachable phone numbers and the associated routes - such a database could be very different for each provider depending on policy.
TRIP is an inter-domain (i.e.,inter-ITAD) gateway location and routing protocol.The primary function of a TRIP speaker,called a location server (LS),is to exchange information with other LSs.This information includes the reachability of telephony destinations,the routes towards these destinations,and information about gateways towards those telephony destinations residing in the PSTN.The TRIP requirements are set forth in [2].

以及第二段中的 The primary function of a TRIP speaker中的speaker我不知道怎么理解,难道是“TRIP功能实体”?
请大家帮我看看,嗬嗬,

积分送上~：）我现在只有25个积分,最多只能送20个,希望大家不要介意,呵呵
文中TRIP是IP电话路由协议Telephony Routing over IP的缩写，呵呵，最主要的是第二段文字中 The primary function of a TRIP speaker中的speaker我不知道怎么理解，恐怕要通信专业的或懂网络的计算机人士给我解答啦，但是都不是我想要的，呵呵，希望懂通信的朋友帮忙理解一下

其实这段文字是RFC3219中的：）
