400電(dian)話能夠(gou)給企(qi)業(ye)經營帶來(lai)很(hen)(hen)大幫助，不(bu)僅(jin)能夠(gou)提高(gao)企(qi)業(ye)的(de)(de)工作效率，也能夠(gou)讓企(qi)業(ye)的(de)(de)人工成本得(de)到控制。但是(shi)從企(qi)業(ye)發展的(de)(de)角度來(lai)看，400電(dian)話申請(qing)費用高(gao)不(bu)高(gao)是(shi)很(hen)(hen)多(duo)(duo)人都在思考的(de)(de)問(wen)題，畢竟企(qi)業(ye)都不(bu)希(xi)望(wang)自己花太(tai)多(duo)(duo)錢(qian)，關于(yu)這個問(wen)題，還是(shi)一起(qi)來(lai)聽聽專家對于(yu)這方面的(de)(de)分析。

那么先從(cong)(cong)400電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)的(de)(de)(de)定義上來(lai)(lai)說。400電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)是(shi)一種主被(bei)(bei)叫(jiao)分(fen)攤業(ye)務(wu)，即主叫(jiao)承擔市話(hua)(hua)(hua)接入(ru)費，被(bei)(bei)叫(jiao)承擔所(suo)有(you)來(lai)(lai)電(dian)(dian)(dian)(dian)接聽費用。從(cong)(cong)現在(zai)來(lai)(lai)看(kan)主要(yao)有(you)：4006電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)，是(shi)中(zhong)國(guo)(guo)聯通的(de)(de)(de)400號(hao)(hao)段(duan)(duan);4007電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)，是(shi)中(zhong)國(guo)(guo)移動(dong)(dong)原(yuan)鐵通的(de)(de)(de)400號(hao)(hao)段(duan)(duan);4008電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)是(shi)中(zhong)國(guo)(guo)電(dian)(dian)(dian)(dian)信(xin)的(de)(de)(de)400電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)號(hao)(hao)段(duan)(duan);4001移動(dong)(dong)新號(hao)(hao)段(duan)(duan)，4000聯通新號(hao)(hao)段(duan)(duan)。但(dan)是(shi)從(cong)(cong)以(yi)前看(kan)來(lai)(lai)企業(ye)電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)分(fen)為(wei)兩種類型：800開頭的(de)(de)(de)后者(zhe)400開頭的(de)(de)(de)電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)號(hao)(hao)段(duan)(duan)。如果是(shi)800電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)對(dui)于撥打者(zhe)來(lai)(lai)說，是(shi)一種完全免(mian)費的(de)(de)(de)服務(wu)電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)，但(dan)是(shi)他一般只支持固話(hua)(hua)(hua)或者(zhe)小靈(ling)通免(mian)費撥打。所(suo)以(yi)現在(zai)800的(de)(de)(de)電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)使用的(de)(de)(de)不是(shi)很(hen)普遍!我們來(lai)(lai)談談400電(dian)(dian)(dian)(dian)話(hua)(hua)(hua)。

400電話(hua)需要電話(hua)人自己承(cheng)擔電話(hua)費(fei)，也就是(shi)說，撥打400電話(hua)不(bu)是(shi)免費(fei)的。

當(dang)我(wo)們(men)撥打400電(dian)(dian)話(hua)時，無論我(wo)們(men)在全(quan)國任何地方撥打，收(shou)取的(de)(de)(de)電(dian)(dian)話(hua)費都是按照城市(shi)電(dian)(dian)話(hua)的(de)(de)(de)標(biao)準收(shou)取的(de)(de)(de)，所以我(wo)們(men)可以給400電(dian)(dian)話(hua)一個更準確的(de)(de)(de)定義：400電(dian)(dian)話(hua)不是免費電(dian)(dian)話(hua)，他(ta)更準確地說(shuo)是400免費長途電(dian)(dian)話(hua)！
