SIP in higher education

[Jeremy George <>]

  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.
