Hi,
I'm not sure if this post will be deemed inappropriate, but I think it's relevant for anyone planning or in the throes of an upgrade/migrate from legacy Nortel or CS1000 systems to Aura and Communication Manager. Particularly if it's a migration over months or years. We have tried help users migrate by further developing our MACs software, PhoneMaster (originally for Meridian and CS1000 systems), to allow you to continue to manage existing Nortel or CS1000 and your new CM all through the same interface. It can even help with the telephone set migration, where you can copy selected telephones from the source telephone system to the target telephone system, preserving extension numbers and names,and using a user-defined Transformation Profile to map features and keys from the source system to equivalent features and keys on the target system. You can migrate a single telephone, a group or all telephones. But the big advantage is the fact it's the same interface, so a minimal learning curve. Anyway, I hope this may be helpful.
