SIPp使用经验

• xml文件，建议``，不建议`ISO-8859-1`
• 命令行传key参数

sipp -key contact_port 9999 ...

• uas send bye

uas send bye的关键是互换from标签和to标签

• uac.xml vs uac_proxy.xml

差别是rrs和route的处理

• do_while循环

# 开始
 
<nop>
  <action>
    <assign assign_to="i" value="0"/>
    <assign assign_to="nloops" value="10"/>
  </action>
</nop>
 
<label id="reg_loop"/>
 
...
 
    <nop hide="true">
      <action>
        <add assign_to="i" value="1"/>
        <log message="i=[$i]"/>
        <log message="nloops=[$nloops]"/>
	    <!-- if i>=nloops then tmp = true -->
        <test assign_to="tmp" variable="i" compare="greater_than_equal" variable2="nloops"/>
      </action>
    </nop>

• SIPp传输模式，这个设计和实现都非常棒

-t  Set the transport mode:
  - u1: UDP with one socket (default),
  - un: UDP with one socket per call,
  - ui: UDP with one socket per IP address. The IP addresses must be defined
	in the injection file.
  - t1: TCP with one socket,
  - tn: TCP with one socket per call,
  - c1: u1 + compression (only if compression plugin loaded),
  - cn: un + compression (only if compression plugin loaded).  This plugin is
	not provided with SIPp.
