We've been stuck with on-premises Exchange because we use it for voicemail, and I've been put off by the fact our voicemail is directly in Exchange UM. That and S4B in 365 is clearly not a solution for us in Australia as they don't do PSTN integration without local SBCs. http://forums.whirlpool.net.au/archive/2578229 But at least now I know there are options if we stick with CUCM (which is fairly likely given our reliance on Informacast). I'm still a bit hesitant as there's 50+ms of latency to our 365 tenancy. > It appears you can do this without CUC, and connect directly to Exchange from > CUCM via a SIP trunk > (http://www.wavecoreit.com/blog/exchange/how-to-setup-cucm-10-5-for-exchange-2013-unified-messaging-voicemail/) > but I don’t know if this will work with a hybrid O365 deployment and you get > a *lot* more functionality from CUC (the main one being IVRs). Exchange UM can do IVRs, although they call them auto attendants. S4B 365 only just got AAs in its Cloud PBX product.

I wonder if it would be possible to use ExpressRoute to talk directly to the Exchange UM SBC from CUCM without having to use your own SBC, like you can do with on-premises Exchange.
