Hi subhash, I think its not a legal scenario.Moreover your quote "The caller probably didn't support TLS but used a sips URL in the initial request so as to ensure secure communication".Assuming only TLS is the standard used to establish secure comm,then how can both be true simultaneously?(Not supporting TLS and needing secure communications)
