There are particular DN's our IP Phone users dial directly but we'd like to prevent them from Transferring, Conferencing, and Call Forwarding to those DN's.
Call Forwarding shouldn't be too much trouble where I would create the following:
1. Create a Blocking Translation Pattern for DN's
2. Create a Blocking Partition to associate to the Blocking Translation with.
3. Create a Blocking Calling Space Space that will include the Blocking Partition.
4. At the Phone Line Level, assign the Blocking Calling Search Space to the Call Forward drop down boxes.
However, this does not resolve my issue with preventing users from transferring and conferencing to the blocked DN's while still allowing to dial those DN's directly.
One idea that comes to mind is utilizing Unity's call routing rules where I would somehow distinguish them based on direct and forwarded calls. However, this might be too complicated. Thoughts?
Anyone have any ideas on how I can restrict transferring and conferencing to certain DN's while still allowing direct calls to them? Thanks in advance.
