幫助企(qi)(qi)業實現企(qi)(qi)業總機(ji)與400電話的互通，支持企業總機所有功能的穿透。不限定中繼線量，便于大話務量用戶使用。400電(dian)(dian)話中繼(ji)(ji)(ji)功(gong)能(neng)(neng):一個號(hao)(hao)碼(ma)(ma)里包(bao)含了(le)多條線路,用(yong)戶對外只需(xu)公布一個代表號(hao)(hao)碼(ma)(ma),但可(ke)以讓多個電(dian)(dian)話同(tong)時打進(jin)來,代表號(hao)(hao)碼(ma)(ma)需(xu)綁定(ding)(ding)(ding)(ding)在(zai)4006號(hao)(hao)碼(ma)(ma)上擴大(da)(da)線路,開通此功(gong)能(neng)(neng)中繼(ji)(ji)(ji)功(gong)能(neng)(neng)后,不限同(tong)時接通線數,取決于中繼(ji)(ji)(ji)容量的大(da)(da)小,比較適(shi)合大(da)(da)型企業。400電(dian)(dian)話號(hao)(hao)碼(ma)(ma)綁定(ding)(ding)(ding)(ding)功(gong)能(neng)(neng):400電(dian)(dian)話可(ke)以免費綁定(ding)(ding)(ding)(ding)20部(bu)(bu),當客(ke)戶有需(xu)求綁定(ding)(ding)(ding)(ding)30部(bu)(bu)、40部(bu)(bu),可(ke)以建議客(ke)戶開通“號(hao)(hao)碼(ma)(ma)綁定(ding)(ding)(ding)(ding)”不需(xu)要開通中繼(ji)(ji)(ji)了(le),比較劃算。而(er)400電(dian)(dian)話的“中繼(ji)(ji)(ji)功(gong)能(neng)(neng)”可(ke)綁定(ding)(ding)(ding)(ding)成(cheng)百上千部(bu)(bu)電(dian)(dian)話,“號(hao)(hao)碼(ma)(ma)綁定(ding)(ding)(ding)(ding)”功(gong)能(neng)(neng)可(ke)綁定(ding)(ding)(ding)(ding)幾十部(bu)(bu)電(dian)(dian)話。如(ru)果(guo)綁定(ding)(ding)(ding)(ding)電(dian)(dian)話少則使用(yong)“號(hao)(hao)碼(ma)(ma)綁定(ding)(ding)(ding)(ding)”更(geng)實(shi)惠(hui)。
