Feedback appreciated,
Yes, it would be wrong to expect performance near that mark. Most
systems cannot handle the TCP processing load generated by a gigabit
ethernet interface, let alone process everything that goes along with
calls associated with that traffic. A TCP offloader engine will help,
but the limitation is still within Asterisk itself. There is a lot that
goes into processing everything related to a call. Now, if you can get
the media to be re-invited to a media gateway, then you can handle
significantly more calls.
My experience is that when you are running media through an Asterisk
server, 240 calls is an average maximum for a typical server.
