Nortel Cics

OK, This is my first question, so please be gentle with me:)

Someone in the trade Telco know the differences between Version 5 and Version 7 of the software running on a Nortel / Norstar Compact ICS?

My current version 5 reads as software version 30cqE00 NP3B in system programming (Feature ** Config)

Are there improvements very interesting between these versions?

Can you choose between the regions A - B & C with the version 7 Feature ** start? (I need to be able to select the region B)

The best answer gets 10 points and thank you:)

Here's the info on the site of Nortel.
