freeswitch 高性能

freeswitch can handle up to 3,000-5,000 simultaneous calls on a performant standard hardware，

When Freeswitch is not used as media server, the capacity of the system (number of simultaneous calls) can be enhanced by a factor 10-20. Thus systems with up to 100.000 active calls can be realized on a single telephony server with a million of users. By using the built-in cluster functionality, these numbers can be even enhanced with several parallel Freeswitch servers.
