Introducing IP-PBX for SME Business

Suilah.com publishes new presentation of VoIP for Business - An Introduction of IP Telephony Technology for Geo-distributed Multi-site Businesses:

Help companies migrating the use of business telephony technology from the traditional TDM-based PBX to the packet-switched SIP-based IP-PBX.

多據點型態的企業在認識到 VoIP 技術後，她們之間只有『淘汰舊技術、採用 VoIP 規劃的進度差異』。這樣的技術當然優先推薦給您。 

由於 IP 分機之間 (全球不論遠近、不論在企業的任一分支處所) 都可『以簡碼一次撥號即直通』，且通話費全免；又，在不同地區辦公室的同事之間要通電話不再須要『層層轉接、用市話 call-out 又再 call-in 到遠端處所』的，團隊之間的電話溝通效率隨即提高。 

另一方面，一般多據點型態的企業在導入 IP-PBX 網路電話總機來建置其跨區域的企業內部分機系統後，市話帳單金額可以比先前使用 TDM 技術的傳統 PBX 電話總機時候減少 30% ~ 40%，想當有感覺。 

在很多的職場裡、在很多很多的時候，辦公桌上的分機電話仍然是最方便、最高效率的遠距團隊溝通工具。電話仍然是工作上重要的工具，比『文字即時簡訊 app』等免費的時髦通信玩具來得有效率。 

讓我們一起來實現：讓『跟在台南、台中、台北的同事講話就像是跟在高雄公司裡隔壁部門的同事講話一樣清楚、方便。』 

其實我們已經做得到讓從 Kaohsiung 到 Osaka, Tokyo, Busan, Seoul, San Francisco, Boston, New York, London, Munich, Istanbul, Dubai, Tehran, Mumbai,... 的電話就像跟高雄 - 鳳山 / 屏東的電話一樣迅速清晰穩定。 

IP 電話、IP-PBX 的花樣還有很多，實在一言難盡。歡迎來電洽詢、吩咐，一同分析、規劃適合您的企業 VoIP 方案。

Suilah, that's it.

Say you are running a business in one of the mentioned categories below:

• Multi-site businesses (多據點營業), such as chained stores (連鎖店), franchise shops (加盟店), distributed points of sales in department stores (百貨專櫃), multi-national companies (跨國企業), etc.

• Businesses with geographical distributed service offices, such as freight forwarders (船務航運業, 物流業), travel agents (旅行社), printing service providers (PSP / 印刷業), etc.

• Businesses with high-mobility operation deployed at non-permanent locations, such as infrastructure engineering firms (土木營建工程公司), real estate sales agents (不動產房屋代銷仲介), event organizers (商展活動主辦 / 會議展覽業者), etc.

Shops in shopping mall: VoIP technology can easily help to better manage and communicate the business of chained retailing networks and geographically distributed shops/companies.

Sure telephony is critically important to carrying on your daily operations efficiently and effectively. But how to build a better and smarter telephony system working for your multi-site businesses? The answer is to use IP telephony technology (VoIP / IP 電話 / 網路電話總機交換機).

(如何建立有效實用的多據點企業電話總機系統? 答案就在 VoIP / IP 電話 / 網路電話技術的應用。讓我們展示一些實績案例給您參考如下。)

IP Telephony vs. Instant Messaging

Desktop instant messaging and mobile instant messaging (即時通信軟體, e.g. Google Talk, LINE, Skype, Whatsapp) are more and more widely adopted as a business telecommunication medium, as a result mainly driven by individual employees using consumer-grade free apps either on PCs or on their own mobile devices at work. However, telephone still plays a very important role of a more effective, more efficient, more reliable, and also more instant way of telecommunication which is a necessary for all businesses.

LINE logo - A popular social instant messaging app.

Those popular in-use social instant messaging apps send text, voice and even video over the Internet, so users can reach contacts out of their workplace conveniently, enjoying mobility and boundary-less communication at none of expenses. This is a significant advantage that instant messaging provides but traditional circuit-switched telephone technology (voice over "PSTN + PBX") doesn't.

Traditional circuit-switched telephone technology (voice over "PSTN + PBX") limits corporate internal telephony network within one premises (i.e. office / building in one geographic location) which does not meet today's needs for a more flexible, portable and secure business telecommunication technology.

Thanks to the use of VoIP technology, there comes a new sort of PBX which can send and receive calls over packet-switched IP networks (e.g. LAN, WAN, Internet) so corporate internal telephony services can be substantially or virtually extended beyond office boundaries. That is, IP-PBX (網路電話總機, IP 電話系統).

Phone Security

The use of public VoIP telephony, which puts the user's voice and the call control signaling data packets transmitted on the public open accessible Internet, largely enhances a corporate's telecommunication capability in terms of operational agility, flexibility, mobility and portability at none of repeat spending on maintaining PSTN (POTS) end-point equipment on distributed sites and/or leasing costly private network connections (VPN). This is even truer for those inter-regional or international businesses.

However, the good of VoIP (especially of public VoIP) also comes with some telecom security issues or risks. As reported by researches (see reference below), in general, it needs more effort and skills to maintain a highly secured communication for VoIP users than for that PSTN / PLMN users (e.g. circuit-switched landline or cellular). Using non-encrypted and non-authenticated VoIP telephony on the public Internet exposes the communication to more threats and risks than using the same on a secured private network.

As can see from the above, applying encryption and authentication measures on your VoIP system may be a doable solution to better secure your phone talk. You can find more information or resources about Secure Communication and Secure Telephone on Wikipedia.org.

While VoIP technology provides strong features of operational agility, flexibility, mobility and portability, it still remains relatively vulnerable and weaker to prevent from either lawful or unlawful threats of phone security issues today, such as wiretapping, remote eavesdropping, intercepting and so on. Still many works to do for making better reliable and secured VoIP uses, and POTS can still last for a foreseeable future. Need not to criticize or laugh on each other technology. Sharing an interesting quote from an Italian wisdom saying:

Declare someone dead before his death and you prolong his life.

But, neither the PSTN / PLMN stays safe and sound all the time. What if big boss wants agencies spying on your phone? Best practice: Off your phone. The old golden rule No. 1 is still true today:

Do not be talky on the phone. Keep matters off the line.

Suilah, that's it.
