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

[Adrian Marsh]

It says in the readme from that link you provided:

	" This patch adds AMR-NB support to Asterisk 1.4

	(for Asterisk 1.6 check out asterisk 1.6 branch and use the 
	asterisk-1.6-AMR.patch patch (provided by Ivelin Ivanov))"

Did you use the 1.6 branch and patch ??

I'll have to try this myself at some point.

Thanks,

Adrian

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

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


Andrea
