8.1.1.8 Contact The Contact header field provides a SIP or SIPS URI that can be used to contact that specific instance of the UA for subsequent requests. The Contact header field MUST be present and contain exactly one SIP or SIPS URI in any request that can result in the establishment of a dialog. For the methods defined in this specification, that includes only the INVITE request.
Nua does not autorespond to the condition of missing contact header in an invite. It's fine for us to do in the application, but would be nice for nua to do for us. There is no completely clear guideline for what we should respond, but we are now using 400 Missing Contact Header as suggested in: https://lists.cs.columbia.edu/pipermail/sip-implementors/2006-March/0123 73.html which seems correct.
