  Well, that's actually a different case.  I use a routing proxy as
a sort of low grade session border controller for inbound calls coming
off-the-local-net to Yale.  SRV records absolutely do come into play there.

  In the outbound case from a Yale phone though, I still don't see
how DNS in involved.  The phone boots and parameters are received
via tftp.  I dial 1234567.  The phone sends that as
sip:
 .  That's the rub.  Homeproxy is
there and there does not appear to me to be an automatic failover
mechanism.
