Inband audio, such as ringing, busy, intercept, silence, etc require transcoding.   We solved the issue on our Asterisk installs by purchasing a hardware transcoding card (for G729, but the card supports several codecs in hardware.     In my experience transcoding happens, accept it and move forward.

I can't help on the first issue, but for the second have you tried doing Set(${SIP_CODEC}=ulaw) before dialing the trunk? I'm in a similar situation where we have g722 internally but our trunk provider only offers ulaw so I see g722->slin->ulaw transcoding. I'm thinking of trying it here (on to troubleshoot our occasional outbound issues.
