[Serusers] wm 4.7 / subscribe error message 500

[Graham Turner]

dear all, have been away from 'SIP' for some while and looking to progress
from where i had left off

i am endeavouring to use Windows Messenger 4.7 (on XP) and where before i
was able to get functional system of two WM clients with iptel.org
registrations to communicate fully this is no longer the case

 am still using WM 4.7 but now on Windows XP (if this should make a diff ??)

the register messages seem to complete ok but fail when i add contacts to my
list - the packet capture indicates a "500 unsupported" message back from
the iptel server in response to the SUBSCRIBE message

it seems there has been some maintenance of the iptel server which late last
week reported in the capture Sip Express router 0.8.14 we know have
0.8.99-dev-tls2

TIA
