The function should work on whatever channel it was set on. If you are going to use it on an outbound channel, then you should use a pre-dial handler to apply it to that channel.

Not a programmer here, just grep -r'ed through the code, but maybe try one of these: G711A G711_ALAW -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

I tried both but none works. maybe this function can not work like the old channel variable SIP_CODEC, which can change inbound call codec. but I do notice something different between chan_sip and chan_pjsip. I use zoiper softphone for testing: when I dialout sip trunk with chan_sip, the remote peer rings, and zoiper now shows what codec to use. if I use SIP_CODEC before dial to change the codec, zoiper will use the new CODEC, but asterisk internal won't change and still transcoding in the middle.(at least core show channel sip/x told me transcoding) when I dialout sip trunk with chan_pjsip, the remote peer rings, but zoiper didn't show what codec to use. only after the callee answer the phone, zoiper shows what codec to use. so it seems chan_pjsip have better chance to do the right thing without transcoding. it's sad that chan_pjsip won't select best codec match two peers automatically without transcoding. but I hope it at least can provide a magic function or channel variable like SIP_CODEC/SIP_CODEC_INBOUND to make correct codec selection.
