Apple is distributing an open-source Asterisk install package for Mac OS X:
A complete IP-PBX in software. It runs on Linux, FreeBSD, MacOS X and
Solaris and provides all of the features you would expect from a PBX and
more. Asterisk does voice over IP supporting all major VoIP protocols (IAX,
SIP, H.323, MGCP, SCCP) and it can interoperate with almost all
standards-based telephony equipment using relatively inexpensive hardware.
? Asterisk also provides Interactive Voice Response (IVR), Voicemail and
Call Conferencing services. It has support for three-way calling, caller ID
services, ADSI, call centre queue management, call monitoring and many more
features. For a more complete list of features please check the Features
section on the official Asterisk project web site.
