[asterisk-dev] AMR support

[chris.2.dobbs at bt.com]

Hi Kevin,
Thanks for the assistance. I was hoping it would be that straight
forward. I have so far managed to build a new codec_amr.c file and am
busily trying hook in the 3gpp amr functions.

Regards,
-Chris

Exactly. Just follow an existing codec_<foo>.c file as a starting point;
the only other changes you will need to make will be in header files to
make the rest of Asterisk aware of the new audio format, and in rtp.c to
assign an RTP codec number to it (if there is not one officially
assigned).
