Asterisk

Asterisk is an open source PBX system, see http://www.asterisk.org/

Asterisk can function as a PBX (Switch), gateway, feature or media server.

Asterisk supports SIP, H.323, their own Inter-Asterisk Exchange (IAX) protocol, Media Gateway Control Protocol (MGCP), and Skinny Client Control Protocol (SCCP).

Inter-Asterisk eXchange (IAX2) - a protocol for calls between Asterisk servers (also implemented by some IP phones) has replaced IAX.

For an example of a system implemented using Asterisk and SER see Max Weltz’s thesis [Weltz 2008].
