[NEW] Make Asterisk 1.4 transparant for all type of codecs


I like to have Asterisk 1.4 running for all kind of codecs. Asterisk just has to to passthrough the RTP without re-encoding or re-transcoding.

DTMF will be no issue, because I don’t use it.
Re-invite is no option for me because I use a server with four LAN port in several subnets with and without NAT.

I tried some patches but none of them works.

Is there a simple configuration change or patch to establisch this?

Kind Regards.
