It’s time to clear up several restraining misconceptions in the telephony space. These are points I outlined during my presentation at AsteriskTag in Berlin recently, though they bear repeating for everyone’s sake.

一、 封软交换平台的端口

 

 

国际电联定义的IP通信信令端口是1719、1720等，终端（不管是软电话、ip电话还是语音网关）连上网后都需要注册到软交换平台，就像QQ上 网要注册到QQ的服务器一样，这样系统才知道这个终端上线了，终端的ip和端口号是多少，并记录下来。有别的终端呼叫这个终端系统就会在数据库中找出这个 终端注册后记录下来的ip和端口号，把数据发往这个地址。

 

 

1、 电信封杀手段

 

 

电信可以封了1719、1720端口，就是在数据包中目的地址的端口为1719的数据包，把这样的数据包处理掉，使终端无法在软交换平台进行数据交换，这个时候，你听到电话连接不通的声音，在平台查看网关注册在线，但是信令不通，电话也就拨打不通。

 

 

2、 反封杀手段

本文本来是自己不久前写的用来介绍TringMe这个免费语音留言/通话插件，今天看到《QQ最新功能预告:QQ音信语音留言》这个新闻，想想腾讯的这个业务肯定是要收费的，想让大家知道除了腾讯也早有其他的类似免费服务存在，愿意用哪个大家自己斟酌。

With over 1500 VoIP providers worldwide we thought it was about time that we have a look at the popularity of these VoIP services and identify the most successfull (at least according to Alexa.com). Most succesfull in this case means the sites with the most traffic and not the most financially viable.

Whenever I discuss Asterisk or Trixbox with someone the questions always comes up... "Does it work with Skype ?". I
was forced to answer no until recently when I came across a new product called ChanSkype . The developers at
ChanSkype have developed a conduit between Asterisk and Skype that enables inbound and outbound calls via the
Skype client on your Trixbox. You can receive Skype calls from other Skype unsers, make unlimited outbound calls via
SkypeOut for $30 更多相关的内容 »
