TeeBX wants to be a VoIP appliance with a user interface to easy manage a communication platform based on Asterisk (forked from askozia pbx). Website, support, documentation (coming soon): http://www.teebx.com/
vTiger Freeswitch Integration by NYFON.
Allows to perform outbound (Click to Call) and incoming (wip) calls from vTiger 6.1+ interface. Modified PBXManager allows to choose between Asterisk and Freeswitch for PBX integration. Same (and extended in the future) functionality as Asterisk interface.
