Your customer has a 10,000-user voice-mail-only deployment. The TDM phone system (not a
Cisco Unified CallManager) that supports all the users is located in the Southern regional office
and the telephone system integration uses a serial connection. You have requested space for the
Cisco Unity servers and they have assigned space in the Northern regional office with the data
servers. The bandwidth between the Southern and Northern regional offices is dial-up via analog
lines. Which statement is true?

A.
This solution will work; the phone system and the voice-mail system do not need to be in the
same location.

B.
This solution will not work; you must provide T1-level bandwidth to redirect the serial integration
data.

C.
This solution will work; the phone system and the voice-mail system can use the analog dial-up
connection to communicate with each other.

D.
This solution will not work; you must have the phone system and the voice-mail system in the
same location, or enough bandwidth to use the remote PIMG option.
