I'd loked at that and thought "Hmm..." and wondered if there was a "newer" 
way...

And I must have glossed over that...

Job done:

   sipsak -M -v -s sip:108 at 192.168.254.100 -B "Lunch time!"
   warning: ignoring -i option when in usrloc mode
   usrloc for 108 completed successful

   All usrloc tests completed successful.
   received last message 4.696 ms after first request (test duration).

At least for Grandstream phones - the Snom300 I have rejects it, but I'm 
sure it's just a matter of reading the manual now ;-)

And I can probably extract the IP addresses of each phone out of the astdb 
without too much bother too. (everything here on the same LAN, so not much 
of an issue)

Thanks!

Just Snom300's for now.
