[asterisk-dev] adding codec+format

[Beñat Urteaga]

Hi,

I'm using asterisk 1.8.8.4 and I'd like to add an audio codec and format in order to be able to send audio to my end SIP devices at a 8 bit 24 kHz. The devices of course support it. How could I get this? I guess I should add codec_whatever.c and format_whatever.c files to the source code directories, but: must I add anything else? For example, may be a SDP negotiation may need to be made, so I should add something else apart from the  codec and format files?



I think format_pcm.c and codec_ulaw.c could be a good starting point (example), but do you recommend something different?

Any help would be much appreciated!!



Thank you!



Ben.
