撰写了基于SIP的meeting压力测试脚本。可以实现同时50个人同时进入meeting，然后说话，12秒后同时退出聊天室，系统等待8秒，再次重复50个人进入会议室，可以实现对meeting的压力测试。
压力测试流程图如下：
invite--------------->meeting
407<------------------meeting
invite with auth----->meeting
100<------------------meeting
user PIN<-------------meeting RTP
DTMF 1 and #---------->meeting RTP
RTP------------------->meeting
pause 18 sec
Bye------------------->meeting
200 ok<----------------meeting

测试csv批量文件如下：
3001;904;[authentication username=3001 password=3001]
3002;904;[authentication username=3002 password=3002]
3003;904;[authentication username=3003 password=3003]
3004;904;[authentication username=3004 password=3004]
3005;904;[authentication username=3005 password=3005]
3006;904;[authentication username=3006 password=3006]
3007;904;[authentication username=3007 password=3007]
3008;904;[authentication username=3008 password=3008]
3009;904;[authentication username=3009 password=3009]
3010;904;[authentication username=3010 password=3010]
3011;904;[authentication username=3011 password=3011]
3012;904;[authentication username=3012 password=3012]
3013;904;[authentication username=3013 password=3013]
3014;904;[authentication username=3014 password=3014]
3015;904;[authentication username=3015 password=3015]
3016;904;[authentication username=3016 password=3016]
3017;904;[authentication username=3017 password=3017]
3018;904;[authentication username=3018 password=3018]
3019;904;[authentication username=3019 password=3019]
3020;904;[authentication username=3020 password=3020]
注意：这里的904号码为meeting接入号。这里我只写了20个，当然您可以写50，100都没关系。
测试方法与步骤：
(1):首先采用eyebeam呼入904号码，进入后根据密码PIN输入1#，进入会议室，然后听背景音乐
(2):采用sipp压力呼入904号码
./sipp -sf meeting.cml -sf meeting.csv -p 6718 -i 192.168.0.254 -m 100000 192.168.0.254 -l 50
(3):此时会听到一批号码登入会议室，然后可以听到一人说话，因为meeting的会议声音是采用叠加技术的，所以会出现很大的回声，之后陆续用户exit，完全退出后会继续听到音乐，因为只有你一个人在会议室了，这说明人已经全部走光了。然后会重复之前的动作
(4):注意 192.168.0.254是发起者呼叫机；192.168.0.194是被测试机。SIpp必须安装在254服务器上才能发起呼叫，另外我这里所指的meeting是指asterisk的conference功能，所以如果有其他软交换要测试会议的话，只需要稍微修改xml文件即可。
