You seem to be confusing addresses in the SIP header and media addresses.
With c= or SOATAG_ADDRESS you put an address in the SDP you're sending out;
that is: The address you want the remote peer to send media to (will
most probably be the host you're calling from).
The other thing is the SIP URI you're trying to call which is a
completely different story.
Creating a TO header works like this:
sip_to_t* to = sip_to_create( NULL, URL_STRING_MAKE(
"sip:alex@192.168.178.82:5060" ) );
nua_invite( handle, SIPTAG_TO( to ), ..., TAG_END() );
Hope this helps,
Andreas
