we’ve already deployed telephony-cost-saving system in my company. first, what’s it? As the name implies, it could save your telephony fee, for example, general telephony fee for dialing out mobile phone, it costs you about 9 NT dollar per minute, and cost-saving system only needs 3.6 NT dollar per minute.
its mechanism also is simple, you only need to install a T1/E1 card on your traditional PABX, and connect it with your carrier’s telephony-cost-saving system. if your PABX already is IP-PBX, then only trunk it with SIP protocol between your IP-PBX and carrier system. the key factor is when your dial out telephone from your internal to external mobile phone, the telephone will route from your PABX to carrier’s system, and reach to the destination.
if so, why do we still need to set up a IP-PABX by ourselves?
因為剛才所說的架構,僅僅只能供桌機使用,無法在智慧型手機使用,所以我自己架一個SIP SERVER的話,再用此IP交換機與節費系統做SIP TRUNK即可..那麼只要在手機裡安裝SIP CLIENT的APP,就能使用手機做節費了..
it’s because what i said above only can be provided for internal desktop phone, it can provide for mobile phone. so if we could set up our own sip server, and let it connect with carrier’s system, then we could use the app of smart phone to do the same thing as above.
ASTERISKNOW 是一套OPEN SOURCE的IP交換機,只要把它下載回來,放在VM上安裝,短短幾分鐘之內,你就能享受手機節費了….
Asterisknow is an open source IP PABX software package, as long as you download it from internet, you could install it completely on your VM environment in few minutes, then enjoy the benefit of telephony-cost-saving.
而且 聰明如你,應該也發現了,你也可以在電腦上裝SIP PHONE,那麼電腦也能通話囉..而且自己架設SIP SERVER,你高興給多少分機就給多少,當然系統本身有一定限制,要看你的系統硬體架構而定,但一般中小企業應該都很好用的…
And if you are smart, you also find out you can utilize it on the computer. if you build up your own sip server, you don’t need to worry about the limitation of extension numbers which might restrict by cost issued by your carrier. the only restriction when you build up your own sip server is your hardware performance. however, i think it’s really enough for mid or middle scale company.
想想,一分鐘若能節省六元好了!! 如果 貴公司一個月全部的人講了一千分鐘的手機好了,就可以節省6千元,不無小補,每天都在省,這種感覺很爽的!!
just think about this, just a assumption, if you can save NT 6 dollars a minute, your company will consume about 1000 minutes a month, then you could save NT 6,000 dollars a month, and always saving the money, it’s really a good feeling.
