[Freeswitch-users] Codec Negotiation. Bug?

[Anto]

Hello

I'm still fighting with the codec negotiation with carriers (as I am
unable to understand how in FreeSWITCH) and I have seen something, I
do not know if it's a bug. If I use a variable in the specification of
output codecs do not see a corresponding message sip, however if
specified in the parameter, if negotiated with the carrier.

<!--global_codec_prefs=VB32,G7221,speex,PCMU,PCMA,BV16,G726-32,iLBC,GSM,G729,G723,AMR-->
<!--carriers_codec_prefs=PCMU,PCMA,G729,G723,AMR,VB32,G7221,speex,BV16,G726-32,iLBC,GSM-->


<param name="codec-prefs" value="$${carriers_codec_prefs}"/>

<param name="outbound-codec-prefs" value="PCMU,PCMA,G729,G723"/>
<param name="inbound-codec-negotiation" value="greedy"/>

Do not understand why in one case send sip message and not in another
(in this cancel the call because it does not handle the negotiation).
What can be?. Thanks !!!
