Just a couple of errors, if you're going to 7.1(2) then you need to use DMA 7.1(2) and not 7.1(5) as you mention.

8.0(1) is deferred, so you might want to choose another 8.0 version.

Table 6     Supported Cisco Unified Communications Manager Upgrades for  Release 8.0(2c)SU1 through 8.0(x)

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html#wp286194

If you go to the downloads for 8.0 you can see which ones have been deferred. Any from the above link are still valid options.

If you want you can go all the way to 8.5, from the link, just look at the 2 previous tables for compatibility info.

Hi Oscar,

I'll try to fill Java's rather large shoes here If it were me I would go with 8.5(1) as I've never

liked the .0 builds due the high number of bugs.

(SU) = Service Update or patch

99% of all builds are classified as "Restricted" which yours will be going forward. Here is

a description of the differences;

Unrestricted Export Support

The restricted US export classification on Cisco Unified CM meant that governmental and military customers in many countries could not employ Unified CM in their networks.

In addition to the delay inherent in obtaining export licenses, products classified as restricted by the Department of Commerce (DoC) carry a requirement to allow US government representatives to demand on-site inspections at any time to confirm that the product is being used in accordance with its licensed purpose. This post-shipment verification (PSV) is unacceptable to many customers.

Additionally, some foreign countries maintain import restrictions which prohibited Unified CM from being available to customers in those countries. Both US export and foreign import issues stem from Unified CM support for strong encryption of signaling and media.

Unrestricted Classification

Because Cisco has obtained an unrestricted classification from the DoC for a version of Unified CM, beginning with Unified CM 7.1(5), both restricted and unrestricted versions of Unified CM will be released in parallel.

Limitations

Signaling and media encryption is permanently disabled in the unrestricted version, but remains unchanged in the restricted version.

Migration from the unrestricted version to the restricted version is not supported.

---

Note No impact exists to other security features such as HTTP(s), SSH, password encryption and authentication (for example, SIP digest authentication), mechanisms used by unrestricted Unified CM clients such as JTAPI, TSP, encryption of SNMP traffic, encryption of data related to database that is done by using IPSEC and IMS on the server side.

The communication between CTL client and provider remains encrypted.
