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

[Евгений]

Hi.
I see you are recording in stereo. Both channels has  horrible quality? I had horrible quality in one channel when it was two interfaces looking in the same network.
Evginey

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.
