[Freeswitch-users] Question aboutCPU usage.

Sat Jan 22 01:41:07 MSK 2011

One solution is to use the GSM codec instead of the g.729 codec.
Although it may not sound as good as the g.729 codec, it uses about
the same amount of bandwidth and less CPU iirc. The GSM codec is
included in FreeSwitch by default.
