That was my understanding too - do you feel it is always working this way in practice though with the major SIP proxies/PBXes? Or are any extra efforts (such as NAPTR for rewriting sip: to sips:) needed to help non-conforming implementations? > See also the thread > "NAPTR, SRV and sips vs. transport=tls" from 1.Dec.2012 > Yes, I did see that previously but the focus of my question was slightly different, hence a new thread > regards > Klaus > > On 11.01.2013 18:45, Daniel Pocock wrote: >> >> >> >> I'm just wondering if anyone can comment on expected and actual behavior >> if there is only a NAPTR record for TLS, e.g. I have: >> >> sip5060.net.
