[cisco-voip] CUCM 8.5 integration with Exchange 2010 for Voice mail

[Gr]

Thanks Nate, Jason! Valuable information, I will keep this in mind.

Another question is we just create voice mail pilot in cucm and route it to sip trunk and then in exchange 2010 we create  voice mail pilot and the actual voice mail ports?

Thanks,
GR
