Hi!

There are some caveats (bugs) resolved in 7.0(2) listed on the Release Notes. It's not a requirement, but you can upgrade your server.

BTW, not sure is you are using Unity Enterprise or Unity Connection.

Please refer to:

*** Release Notes for Cisco Unity Connection Release 7.0(2) ***

--> Upgrading from Cisco Unity Connection 7.0(1) to 7.0(2)

--> Upgrading to Cisco Unity 7.0(2)

This is a straight upgrade.

Regards,

Teresa.
