Hi all, I have a project for the 3G related, AMR and AMR-WB support.

I’m using the client develop suite from the PortSIP(http://www.portsip.com),
as their said
support the AMR, AMR-WB with RFC4867.

Now I have to setup a SIP server/SIP PBX in our Lab for test, does the
Asterisk
support these codecs and RFC4867 ? If no, there has any plugin to support
this ?

Also, any other Server/PBX which support AMR, AMR-WB recommended are
welcome.

Best regards,

  • I patched asterisk once 2 years ago but couldn’t exactly remember the
    way or link

    may be one of these that google showed me today.

    you can give a try

    http://www.howtonix.com/amr-codec-for-asterisk-1-4-and-1-6/

    http://sourceforge.net/projects/asterisk-amr/

    It worked for me, by chance I have cli output in my mail which I sent
    to my manager after installing the codec.
