It's a good question. When I wrote the section tls was really only
a gleam in the IETF's collective eye. I forget my source offhand, but
it was probably a ID draft. As Steve notes in a later reply it still
isn't widely deployed.

This section of the cookbook might usefully be updated though.

As an overall reply, I don't think there's a negative to putting
both in your dns tables. I'm not sure it's relevant to contemporary
UAs but older ones used non_underbar domains. As in:

sips.tcp.bigu.edu. 43200 IN SRV 0 0 5060 sipserver1.bigu.edu.

The cookbook shows

_sips._tcp.bigu.edu. 43200 IN SRV 0 0 5060 sipserver1.bigu.edu.

Other examples I've seen use:

_sip._tls.bigu.edu. 43200 IN SRV 0 0 5060 sipserver1.bigu.edu.

Should I be using both?
