官方的性能报告：
Kamailio (OpenSER) 1.2.0 - Transaction Module and User Location Performance Tests
如下的提取的性能参数也是基于官方的性能报告，信令走的UDP，作为做系统方案的参照，Kamailio的性能还是非常，非常优秀！
All used SIP-related software was configured to use UDP as transport protocol for SIP.

不同线程数性能报告：
如此高的性能，搞个双机热备作为信令服务，然后媒体服务freeswitch搞个分布式，如此的可靠性的呼叫平台就非常的优秀了！
