First suggestion: use
su_log_set_level(NULL, 9);
to increase verbosity of sofia-sip, that's bloody helpful.

I think the problem here is that you didn't specify any SDP
capabilities, try for example with:
nua_invite(op,
SOATAG_USER_SDP_STR("m=audio 5004 RTP/AVP 0 8"),
NUTAG_URL(to_url),
/* SOATAG_ADDRESS("0.0.0.0:8000"), */
NUTAG_EARLY_MEDIA(1),
TAG_END ());
Note also that SOATAG_ADDRESS seems to conflict with SOATAG_USER_SDP,
when they both are present the call seems to fail, the sofia-sip stack
logging also doesn't help, and I currently don't understand what's
the meaning of that tag.
