[cisco-voip] Unity SMTP Domain Change

[Anthony Holloway]

Just my two cents on this: if "unitya" is the hostname name of the 11.5
system, and "unityb" is the hostname of the 12.5 system, I would not use
"unitya" on 12.5.  That's just a "typo" waiting to be corrected by someone,
which then would break things.

So, while you can change the domain to be anything you want on the 12.5
system, to include "unitya", I would shy away from it, from a cleanliness
of data/configuration standpoint.

That's just me.  But, if you have no other choice, because the alternative
is too expensive or complicated, then you gotta do what you gotta do.

For future reference, as long as you're not networked to another CUC
system, just change the 12.5 to something even more generic (e.g.,
"voicemail.domain.local") which might help with this kind of thing in the
future (e.g., v14).
