star — Fri, 08 Apr 2011 08:17:00 +0000

The Sippy RTPproxy is a high-performance software proxy server for RTP streams that can work together with SIP Express Router (SER), OpenSIPS, Kamailio, Sippy B2BUA or reSIProcate B2BUA.

The main purpose of RTPproxy originally had been to make the communication between SIP user agents behind NAT(s) (Network Address Translator) possible.

Howto: Voip Performance test – SIPp

star — Mon, 21 Feb 2011 06:26:21 +0000

Homepage: http://sipp.sourceforge.net/

测试软件
SIPp v3.2-TLS-PCAP, version unknown, built Feb 17 2011, 10:19:21.

安装编译：
下载源代码后重新编译
# wget http://sourceforge.net/projects/sipp/files/sipp/3.2/sipp.svn.tar.gz/download?use_mirror=ncu
# tar zxvf sipp.svn.tar.gz
# cd sipp.svn
# make pcapplay_ossl

备注：测试RTP需要pcap包，测试认证需要OpenSSL包，e.g.
* C++ Compiler
* curses or ncurses library
* For authentication and TLS support: OpenSSL >= 0.9.8
* For pcap play support: libpcap and libnet
* For distributed pauses: Gnu Scientific Libraries

测试脚本命令
sipp -sf meeting.xml -inf meeting.csv -l 60 -m 60 -i 192.168.1.67 192.168.1.40:5060

测试流程
1. 创建会议接入号：10000；
2. 创建会议：123456，密码：123；

X-Lite – free SIP phone (VoIP) client under Linux

star — Wed, 13 Jan 2010 08:09:26 +0000

成功安装使用 X-Lite 2.0 for Linux，效果不错的，就是配置要注意些。
该版本只有语音而没有支持图像，看来其开发的重点还是 Windows/Mac。

备注:
Linux Deepin 9.12 (Ubuntu 2009-11-03) 缺少了 libstdc++.so.5 库，按照下面的方法安装: Getting 32-bit libstdc++.so.5 in Karmic Koala on a 64-bit system
看不到的同学直接下载安装: http://packages.ubuntu.com/jaunty/i386/libstdc++5/download

———————————–
X-Lite 是一种特有VoIP软件电话的免费软件，使用会话发起协议。X-Lite 由位于温哥华的一家CounterPath软件公司所开发。
X-Lite 目前主要有两种不同的产品。X-Lite 2.0 使用于Linux平台，是使用旧式的 X-Pro code base, 而 X-Lite 3.0 是使用于 Windows 和 Mac OS X，使用 eyeBeam code base. X-Lite 2.0 只有声音，没有影像。X-Lite 3.0 则兼具声音和影像。
2005年，本产品荣获 Internet Telephony 杂志的年度最佳产品.

Google Voice 注册成功，号码比较好记，正常呼出和呼入

star — Thu, 23 Jul 2009 03:23:42 +0000

以下内容仅供测试研究。

Step 1:

Apply one Google Voice account, e.g. one free US phone number. You should use the proxy to access Google Voice, it will spend several days.

For the China subscriber, refer to: http://google.org.cn/2009/07/15/how-to-signup-google-voice-in-china-mainland/

Step 2:

Apply one Gizmo5 account, e.g. one SIP Phone number, one user name and password. It will be taken affect immediately, but a slug of network is from China.

Refer to: http://www.jrin.net/2009_07_26/use-gizmo5-for-free-calls-with-google-voice

Step 3:

Make a connection between Google Voice and Gizmo5 accounts.

Refer to: http://www.jrin.net/2009_07_26/use-gizmo5-for-free-calls-with-google-voice

Created 2009/07/23

关注google voice一段时间了，昨天终于注册成功，号码是(518) 594-1818。
参考下面的文章：国内注册 Google Voice 的方法

考虑到www.virtualphoneline.com的号码只有24天试用期，从ipkall.com重新注册了个号码，免费而且无期限:-)
各位TX谁要是也申请了，可以给偶语音留言。持续关注……

Updated 2009/07/28
从谷奥那里获知通过Gizmo5和Google Voice一起使用可以完整的打入和打出电话，根据网上的资料操作成功，呼叫时间未测试。
参考下面的文章：
最初的消息来源：Gizmo5+Google Voice=GizmoVoice

Howto: tcpdump user guide

star — Tue, 12 Aug 2008 02:16:56 +0000

示例1：指定网卡，抓包到文件
# tcpdump -i hme0 -w /tmp/sms.cap
-i xxx Interface
-w xxx write into file

示例2：指定网卡，指定端口，屏幕打印，抓包完整内容
# tcpdump -A -n -s 0 port 5060 -i eth1
-A print ASCII
-n keep IP address
-s 0 capture all data for each packet
port xxx captured the port

1. 命令格式：
tcpdump [ -adeflnNOpqStvx ] [ -c 数量 ] [ -F 文件名 ]
[ -i 网络接口 ] [ -r 文件名] [ -s snaplen ]
[ -T 类型 ] [ -w 文件名 ] [表达式 ]

2. tcpdump的选项介绍
-a 　　　将网络地址和广播地址转变成名字；
-d 　　　将匹配信息包的代码以人们能够理解的汇编格式给出；
-dd 　　　将匹配信息包的代码以c语言程序段的格式给出；
-ddd 　　　将匹配信息包的代码以十进制的形式给出；
-e 　　　在输出行打印出数据链路层的头部信息；
-f 　　　将外部的Internet地址以数字的形式打印出来；
-l 　　　使标准输出变为缓冲行形式；
-n 　　　不把网络地址转换成名字；
-t 　　　在输出的每一行不打印时间戳；
-v 　　　输出一个稍微详细的信息，例如在ip包中可以包括ttl和服务类型的信息；
-vv 　　　输出详细的报文信息；
-c 　　　在收到指定的包的数目后，tcpdump就会停止；
-F 　　　从指定的文件中读取表达式,忽略其它的表达式；
-i 　　　指定监听的网络接口；
-r 　　　从指定的文件中读取包(这些包一般通过-w选项产生)；
-w 　　　直接将包写入文件中，并不分析和打印出来；
-T 　　　将监听到的包直接解释为指定的类型的报文，常见的类型有rpc（远程过程调用）和snmp（简单网络管理协议）
