PJSIP在Asterisk12中被集成进来，作为asterisk第二个SIP协议栈。以下是安装步骤，记录下来已备忘。首先安装版本控制工具git，在这里只是下载pjsip的代码；下载git-1.8.1.5到/home目录内：# cd /home# tar zxvf git-1.8.1.5.tar.gz# cd git-1.8.1.5下面编译安装：# make prefix=/usr/local install二进制文件会被安装到/usr/local/bin目录里；系统上已经安装过git的，此步可

IPV6的时候涉及到一个概念，link-local address, 中文叫“链路本地地址”，它的前缀是FE80::/64一个link-local address的范例：FE80::713e:a426:d167:37ab实际上，这个概念类似于ipv4中，当DHCP分配失败时自动生成的169.254.XXX.XXX这样的地址，凡是源地址或目的地址中含有link-local address的报文，路由器都不应当转发它。这样的报文只能在一个LAN中互通。＜IPV6的地址类型＞可分为三大类：1、单播地址
