Hi, Should be possible, however the media framework will need clock generator, you can employ null audio device as clock generator, please see pjsua_set_null_snd_dev() doc. However, if your hardware codec has clock generator, I think it'd be better to integrate it as "sound device". And for clarification, PJMEDIA_SDPNEG_NOANSCODEC error is a different issue.
