freeswitch
FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a versatile software implementation that runs on any commodity hardware. From a Raspberry PI to a multi-core server, FreeSWITCH can unlock the telecommunications potential of any device.
Oh, and if Asterisk isn't your thing, check out FreeSwitch - another rock-solid open source option that's been powering VoIP systems since 2006. It was actually created by former Asterisk developers who wanted to build something more modern. Go figure. ¯_(ツ)_/¯
