隨著寬頻網路的發展及多媒體相關技術的成熟與普及，網際網路電話服務已逐漸成為語音通訊市場中的主流。為了提供用戶連線需求，負責連結網際網路電話與傳統電信電話的閘道器數目勢必亦將隨之攀升。因此，以傳統靜態設定方式來管理閘道器的網路位置與其所對應的電話首碼將不敷所需，為了提供一個自動化且滿足網際網路電話路由全域性的解決方案，網際網路工作小組提出了網際網路通訊協定上的電話路由協定。網際網路通訊協定上的電話路由協定為一跨領域的網際網路電話閘道器路由協定，其在應用層所扮演的角色就相當於網路層中的自治系統間路由協定，而後者之一個最廣為人知的例子就是邊界閘道器協定，因此，網際網路通訊協定上的電話路由協定的行為觀念有許多是由邊界閘道器協定而來。而在同一個電話領域內的路由則由電話閘道器註冊協定來負責。我們實作網際網路通訊協定上的電話路由協定之外，並採用會議初始通訊協定作為控制信令協定，搭配評價極佳的開放原始碼會議初始通訊協定代理伺服器, 即會議初始通訊協定高速路由器上進行程式模組的開發。最後，並以實驗測試數據來說明網際網路通訊協定上的電話路由協定所帶來的益處。

Recently, because of the maturity of Internet and the increment of network bandwidth, the telecommunication of the IP based services become more and more popular. Internet voice services, known as VoIP, also popularize gradually. Due to the rapid growth of VoIP, the gateways connected to the Internet telephony and traditional telephony network, PSTN, will increase more and more to support the service connection requests. Many gateways could complete a call. They are not efficient for manual setting nowadays. In order to support a dynamic setting and meet the routing capabilities of the Internet telephony, IETF introduces the Telephony Routing over Internet Protocol. TRIP is an inter-domain IP telephony gateway routing protocol. TRIP runs at the application layer, just like the inter-Autonomous System routing protocol runs at the network layer, where one well-known protocol in that layer is the Border Gateway Protocol Version 4 (BGP4). Hence, TRIP is modeled after the BGP-4 and enhanced with some similar features. We implement the TRIP protocol stack, choose the SIP to be the signaling protocol, and select the well-known SIP proxy, SER, to run with our programs. At last, we will show the experimental results to explain the advantage TRIP brings.
