I didn’t see any mention of this on the VoIP blogs I read, but it seems to be worth noting.
FreeSWITCH version 1.0.0 was released on May 26 after about three years of development. I would call it a cross between Asterisk and OpenSER. It’s robust like OpenSER but has more base features similar to what Asterisk provides. Makes sense, as the developer is a former Asterisk developer.
Interesting blog post: How does FreeSWITCH compare to Asterisk?
It’s designed as a soft-switch, not a PBX (see FAQ) but you can add the PBX features on to it that you want. I think this will be a real competitor to Asterisk, sipX and whoever else in the free/open-source world.
Junction Networks offers some cool services including hosted conference bridges, which they’re powering with FreeSWITCH.
