There are a couple modules that could greatly benefit from a bulk import/handling option:
-Inbound Routes (DID, Description, Destination, MoH, Recording, Privacy)
-Endpoint Provisioning (Extension, MAC, Brand, Model, Template)
Additionally, there are a few fields that should be added to the existing bulk import/export for Extensions, as they are already present on bulk modification:
-CID on Diversion (caller/callee)
-MoH
