本狗不懂IT, 这也不是IT  , 我玩VBUZZER是用一个ENGINEERING SAMPLE, 不花钱的东西不玩白不玩你也不用不好意思, 我修车是自学为主, 都是从不知道到知道, 我以前不懂车的时候, 也买过一台全新99 COROLLA, 那时候SALES说98以前的都是1.6小发动机, 不如买全新车是1.8大马力发动机, 我就上当了, 后来本狗虽然在小修车行玩过周末零工, 也没接触过旧款COROLLA搭载1.8发动机, 通常不太流行的车型的特殊配件大多难找而且昂贵, 新旧款1.8很多配件不通用, 你的DX岁数慢慢大了, 要小心点好好保养好好呵护啊 |

我接触vbuzzer也是非常偶然，9月份搬家，先后问了Bell和Rogers，一个要收我55$的安装费，每次搬家还要继续收；另一个一定要加一个feature如来电显示，气得我只好试用vbuzzer，11月初买了Sipura 1001后越用越觉得好用，特别是直拨中国的功能，对老人太方便了，所以才发这个贴介绍我的使用经验。 |

个人感觉Sipura 3000 作为家用,用处不大
作为商用, 功能又太有限. 家用: you have to subscribe one legacy land phone line(from Bell or Sprint), also to make the VOIP work, you have to subscribe one VOIP service from provider (like vbuzzer for GTA, or other providers in other cities). 商用: I prefer to use open source software Asterisk + Digium cards. Digium has all kinds of cards support connecting to one legacy phone line or even T1, which is 23 regular phone lines. Asterisk is a powerful open source pbx software, with it, you can set up your own phone system in your company or your home. You use Digium cards to connect to PSTN, inside your office, you use VOIP. I set up one test environment at my home using X100P card, only has one FXO port, just for fun. I created greeting message, created extensions, routing incoming phone calls from PSTN to my voip extensions, also making outgoing calls from voip extensions. I can also left a voice message to my extension, then the Asterisk send the .mp3/.gsm format message to my email, which is the same as VBUZZER. I guess the backend of VBUZZER is asterisk too. In the VOIP world, the bigger player will win the game. bigger players means players with big user bases. Just think about this case : there are 100 telephone users, 70 are Bell users, 10 are vbuzzers, and 20 are other provider users. If users make phone calls within vbuzzer subscribers, then vbuzzer doesn't need any PSTN/T1 connection to Bell or Sprint, all the cost is just the internet traffic. But if 3 of 10 vbuzzer users want to make phone calls to Bell users at the same time, then vbuzzer has to prepare at least 3 PSTN lines which connect to Bell/Sprint, this way the cost goes up. Skype is VOIP system, but it is not open, that means you have to use its own client, which is Skype messenger software. Also Skype doesn't provide PSTN numbers, that is reasonable because Skype is targeted to be global voip provider, if it tries to give each user a PSTN number, Skype has to deal with Telecom department in every city/country. When Skype user bases grows to a very large number, you will see, you don't need a phone number any more, all you need is just your skype ID. That is why so many internet giants are so dedicated to the instant messenger market. At that time, Bell will disappear from the world if it still not taking actions. this is a horrible picture, but it is not impossible. Just think about the long distantance phone company like AT&T. VBUZZER is just a temporary solution, it will survive until the legacy telephone system becomes minority. Also, if VBUZZER can not get enough subscribers, it will ...... disappear. It is cruel, but this is the rule. 引用:

SPA-1001的COUPON
多谢EV_Huang & Buner的信息 根据Burner的TIP, 再那个VANCOUVER的公司ORDER了SPA-1001, 下单的时候看到能填COUPON, 就GOOGLE了一下, 发现如果用*user作为COUPON,能省近$4 shipping free, + GST后共给了71.10CAD 等试过这个SOLUTION好用后, 就把COMWAVE停了, 因为最近发现不那么稳定, 打着打着电话就嗡嗡嗡的响(断线了). |
