FreeSWITCH scores highest at 85/100, with 70 commits in the last 90 days, 5.1k GitHub stars and its latest release (v1.11.3) published 17 days ago. FusionPBX has the most raw commit activity at 206 commits in 90 days.
2 of 5 are permissively licensed (MIT, Apache, BSD or similar): FreeSWITCH (MPL-2.0), FusionPBX (MPL-1.1). 3 use copyleft licences such as GPL or AGPL, which require you to publish changes if you distribute a modified version.
None of the 5 tracked alternatives currently advertise Docker support, so expect manual installation. Docker support is worth 10 of the 100 health points on Repoly.
