Home-grown.

Yes we do. Sorry, can't go into details for obvious reasons.

I don't know about the performance of FreeSWITCH. All I say is that a
generic server can transcode >5k calls in software.

Quite a few years ago at a ClueCon I tried explaining how everyone was
writing VoIP software the wrong way and how they were throwing
performance out the window. You were there Nenad. :) Admittedly I was
fairly drunk so I probably did not sound very convincing... ;)

5k calls is ~500 kpps, not a problem on any non-ancient server NIC.
