Can we use Batch Provisioning in the Intrado portal to upload the entire range of possible extensions, 1000-9999?
Do we need EHDU and Softphone extensions ex. 1*000, 10*00, 100*0?
How about Device Only phones (Agent phones) ex. **1000
I feel like we can just upload everything and never worry about new employees/extensions ever, but don't know enough to do it and we don't want to mess it up.
