[Freeswitch-users] How to avoid transcoding?

[Ulrich Backes]

Hi guys,

I've investigated many hours and cannot solve this problem:
A and B should use g711u. 


A:  


B:  

But FreeSwitch decides to transcode:

 
The settings:
vars.xml
<X-PRE-PROCESS cmd="set" data="media_mix_inbound_outbound_codecs=false"/> 
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,G722,PCMU,PCMA,VP8"/> 

internal.xml
<param name="inbound-codec-negotiation" value="greedy"/>
<param name="inbound-late-negotiation" value="true"/> 
<param name="disable-transcoding" value="true"/> 

<param name="inbound-proxy-media" value="false"/> 
<param name="inbound-bypass-media" value="false"/>
<param name="inbound-codec-prefs" value="$${global_codec_prefs}"/>
<param name="outbound-codec-prefs" value="$${global_codec_prefs}"/>

default.xml (Using the demo-Dialplan)
<extension name="Local_Extension">
...

Using FS v 1.8

Thanks.
Uli
