摘要註:	隨著網際網路的盛行，大多數的企業也漸漸採取以SIP協定的網路電話(VoIP)系統服務。目前VoIP傳輸模式分為兩種：一種為點對點架構，另一種為主從式架構。由於IPPBX皆使用主從式架構的傳輸模式以方便解決使用者位於NAT網路環境所產生的問題，然而主從式架構的傳輸模式最大的問題在於使用者人數的增加將造成IPPBX網路環境與系統本身效能上的瓶頸。對於一般大型企業因為使用者數量與總公司與各分公司之間的需求，必須設置數量龐大的IPPBX機器，因此將產生一些問題，例如：如何管控數量龐大的IPPBX機器、各IPPBX之間的連接、scalability的問題以及與一些服務或異質網路連接等。因此本研究提出了一個階層式的VoIP系統，此系統使用一台點對點傳輸方式的伺服器來管理以及連接各IPPBX，伺服器主要是負責建立不同IPPBX底下使用者會議的建立，而各IPPBX則用來管理與負責底下所屬使用者會議的建立，而也使用一台IPPBX負責連接其他異質網路，透過此系統架構可以解決管理上與連接上的問題，且可以與其他異質網路作連接。 Due to the prevalence use of internet, many companies are using SIP as the protocol for the telecommunication system VOIP. Presently, VOIP transmission is divided into two forms, one is peer to peer mode, and another is client server mode. Most of the company are using client server mode, solving the problem for users that are behind NAT, but in client server mode, the perplexity of IPPBX environment and the load of the system will increase with the raise of the user. Cause to the reasons of the numerous of users , and the need of branch company to contact with the head office, large company needs to setup numerous of IPPBX, therefore, facing within problems like management of numerous IPPBX、connection of each and every IPPBX、connection of heterogeneous service and network, by solving the problems just mentioned, our theme proposed a two layer VOIP system. Our system uses a proxy server as entrance which not only is capable to provide peer to peer transmission mode, but also manage and connect each IPPBX under the system. The main proxy server is used to initial sessions for user that are not under the same IPPBX, and the IPPBX is used to manage and responsible for the users under it. By adding an extra IPPBX for connecting heterogeneous network, our system not only provides connection to heterogeneous network, but also solves the problem of the management.
