High capacity switching
FreeSWITCH rocks! We replaced 10 asterisk machines with a single instance of FreeSWITCH. Of course with all of the left over hardware we went ahead and made a small cluster for redundancy.
We're using FS to handle approximate 300 simultaneous SIP calls (i.e. 600 legs) with media handling on a two-proc Xeon 3.2 ghz box. CPU utilization is roughly 10% (mostly due to network I/O). Works beautifully. Simple to setup, intuitive to configure. Highly recommended.
I'm using FreeSWITCH just as a "dummy" PBX. I can do this thanks to the flexible design of FS.
I dont use the default XML dialplan. Instead I provide a custom dialplan (containing just one entry) when a new call comes through the mod_xml_curl interface. This allows me to dynamically change the location of each extension at any time.
I dont use the default XML directory either, each user are fetched from my own server (through mod_xml_curl) each time it's registered.
Finally I monitor all extensions (BLF) by using the event socket (mod_event_socket)
We have used FreeSWITCH for independent calls to emergency staff, relying on it for medical purposes.
We have used successfully a combination of OpenSER and FreeSWITCH to build a media aware SBC. Call recording interception, transcoding. Works like a charm.
Will soon post an how to.
We use FreeSWITCH as the PBX in a law office with 190 extensions. Some of the features used that Asterisk couldn't give us: accurate BLF, park orbit groups, rollover lines for extensions and custom ringtones. Brian Snipes <firstname.lastname@example.org>

FreeSWITCH For a Service Provider
I started here but I got a little carried away. I dropped it on my blog.
Good job using FreeSWITCH
I started learning FreeSWITCH in 2008. In August 2009 I got a job using FreeSWITCH in Algeria Telecom just because of a simple integration with Skype and FreeSWITCH for demonstration purpose., in adition to a simple complain about the SIP blocking that AT are doing to block VoIP calls and let clients use their analog network ;)
