IM based on SIP can be done poorly by using MESSAGE method or properly by using 
MSRP media plane. Policy to allow or deny incoming requests is up to the 
end-points. XCAP typically stores Presence related policy. Nobody stops you to 
extend such presence rules to session requests and implement an OpenSIPS module 
to query them but it would be s a stretch of imagination.
