Would Unity Connection would be a optimal solution for the following design:
Call Manager 6.x and IPCC are in UK with 185 IP Phones.
SRST site in Netherlands with 180 IP Phones
SRST site with 80 Users in France, and 80 in Italy respectively.
We were gonna with Unity Express at each location connecting to Call Manager in UK, but then thought of implementing Unity Connection in UK where the Call Manger is and supporting the local site in UK as well as remotes sites through out the Europe through Unity Connection
