[asterisk-users] AMR codec for Asterisk 1.6.1.X

[Andrea Cristofanini]

Hi list,

Anyone have successfully compiled amr codec for asterisk 1.6.1.X ?
I still have no problem compiling and playing with it on Asterisk 1.4.X.

I have used the following patch  :
https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/amr/

Hare is what i get while loading codec_amr.so

debbi*CLI> load codec_amr.so
  == Parsing '/etc/asterisk/codecs.conf':   == Found
    -- codec_amr: parsing codecs.conf
    -- codec_amr: set octed-aligned mode to 1
    -- codec_amr: set dtx mode to 0
    -- codec_amr: AMR mode set to MR122 (7)
codec_amr: enc_mode = 7, dtx = 0

The CLI does not show codec audio or codedc translation for AMR NB.

Anyone have any idea ??

Thanks in advantage
