1、成本在你建立任何東西之前，成本可能是**重要的考慮因素。在你開始從事某項(xiàng)業(yè)務(wù)之前，你首先想到的是--我要花多少錢？你不想投資任何你無法持續(xù)下去的東西。獲取該區(qū)域所有服務(wù)提供者的報(bào)價(jià)，并查找每個(gè)服務(wù)提供者的優(yōu)缺點(diǎn)。網(wǎng)上的在線評(píng)論網(wǎng)站，江北區(qū)SIP話機(jī)，江北區(qū)SIP話機(jī)，也可以為你提供你正在尋找的信息。通常IP電話系統(tǒng)連接附帶一個(gè)包，比如無限呼叫訪問，基本排隊(duì)管理等等。對(duì)于您的組織來說，這些特性可能很重要，但是價(jià)格是選擇服務(wù)的**重要的決定因素。如果你想建立你的業(yè)務(wù)IP電話系統(tǒng)，一個(gè)可靠的互聯(lián)網(wǎng)可能是**基本的和默認(rèn)的事情。如果沒有可靠的互聯(lián)網(wǎng)，在你的工作場(chǎng)所安裝IP電話系統(tǒng)是毫無意義的。隨著通信技術(shù)的發(fā)展，網(wǎng)絡(luò)連接的可靠性和快速性變得越來越容易，建立IP電話系統(tǒng)的過程也越來越簡(jiǎn)單。綜上所述，確保你有一個(gè)很棒的互聯(lián)網(wǎng)是轉(zhuǎn)移到IP電話系統(tǒng)**基本的事情。</p><div

SIP協(xié)議設(shè)計(jì) SIP**早由Henning Schulzrinne和Mark Handley于1996年所設(shè)計(jì). SIP的設(shè)計(jì)目標(biāo)之一是提供類似公用交換電話網(wǎng)（PSTN）中調(diào)用處理功能的擴(kuò)展集。在這個(gè)擴(kuò)展集中，實(shí)現(xiàn)類似日常電話的操作：撥號(hào)，振鈴，回鈴音或者忙音，只是實(shí)現(xiàn)方式和術(shù)語有所不同。 SIP也實(shí)現(xiàn)了許多七號(hào)信令系統(tǒng)（SS7）中更高級(jí)的調(diào)用處理功能，盡管這兩個(gè)協(xié)議相差很遠(yuǎn)。SS7是一個(gè)高度集中處理的協(xié)議，其特點(diǎn)表現(xiàn)為高復(fù)雜度的中心網(wǎng)絡(luò)結(jié)構(gòu)和無智能的啞終端（傳統(tǒng)的電話機(jī)）。SIP則是一個(gè)點(diǎn)對(duì)點(diǎn)協(xié)議，所以它只需要一個(gè)相對(duì)簡(jiǎn)單的（因此也高度可擴(kuò)展的）**網(wǎng)絡(luò)，而將處理工作下放給連接在網(wǎng)絡(luò)邊緣的智能端點(diǎn)（裝有硬件或軟件的終端設(shè)備）。SIP的許多功能在端點(diǎn)中實(shí)現(xiàn)，這與傳統(tǒng)的SS7將其在網(wǎng)絡(luò)**設(shè)備實(shí)現(xiàn)的作法大異其趣。</p></p><br
