FreeSWITCH supports amr in passthrough mode only. Not sure about the rfc 4867 part. On Jun 14, 2012 8:54 PM, "Jakson Kalsson" <sipmaillist@gmail.com> wrote:

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 Freeswitch support these codecs and RFC4867 ?

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

Best regards,
