I have found discussion thread on how to secure e.g. TEL URI over SIP from 2007. 
transport=tls is deprecated and it does not mean end to end anyway.
We still do not have "tels" URI.

Was this discussion concluded and if how it was concluded?


AFAIK there was never any resolution of this - nobody knows how to do it.
I think the most fundamental problem is that there is no good answer to who is permitted and able to authenticate the use of a particular TEL URI.
