I would expect the same to happen if the PUB went down and access to the SUBs was still available.

Can I assume that during this time, no logins or logouts would be possible?

  I just tested with a 7970 and when the phone drops into SRST mode it  
  keeps the EM profile dn(s).  Since you don't configure ephone/dns in  
  SRST the phone keeps whatever dns it had before it unregistered with CM.

  will not work in SRST since the EM service runs on CCM
  which is not longer in the picture
