[Asterisk-Users] Testing two E400P with E1 cross-cable

[Steven Critchfield]

Something for you to think about, your machines should be more than
powerful enough to move that much data. If the system load is high,
maybe you might want to look into what file type you where playing on
the line to simulate the call. If it is playing a mp3, or a GSM file
there is decompression and a lot of context switching going on on top of
dealing with the calls.

I think you should first look into compiling your own kernel. You will
sometimes see a pretty significant speed difference in just that. Then
maybe look into the codecs being used. Try converting to slinear so
there is no real compute load outside of the servicing of the E400P.
