[Freeswitch-users] Recording all calls with good quality.

[brandon.mcginty at gmail.com]

I've tried the following codec settings, set in vars.xml. The first and third lines are the defaults upon install.
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=G7221 at 32000h,G7221 at 16000h,G722,PCMU,PCMA,GSM"/>
<!--tried both the following lines. Quality did not change noticeably-->
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=G7221 at 32000h,G7221 at 16000h,G722,PCMU,PCMA,GSM"/>
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,GSM"/>
My CPU load shows fine, even with 2 clients connected to an external (secondary) switch, through this one.
I truly appreciate the help.
