We have two Unity 5 systems integrated with the same AD forest (different child domains) and connected to different Call Manager clusters that use site codes to route call between.
One site uses 4 digits extension and the other uses 3 digits extensions, so they are unique and our plan was to use Digital Networking between two systems.
1. Is it possible to automatically prepend sitecodes when using Diretory Handler and Auto Addendant? In this case Unity will hand it over to Call Manager with site code prepended and Call Manager will be able to route the call.
How about message forwarding?
2. Two Unity 5 systems are geographically dispersed with about 200ms round trip latency.
Are there any implications on using Digital Networking in this case?
