FreeSWITCH 支持許多高級的 SIP 特性,例如 presence/BLF/SLA 、TCP TLS 和 sRTP,它還可以用來作為類似于 SBC (Session Border Controller) 的透明代理。

Removal of several in tree third party libraries and many updates related to this change means new support libs from SQLite, OpenSSL, an more.
A large number of security and stability improvements that have been found by making FreeSWITCH compile with various compilers and by reviewing the code base with Coverity.
