In a Microsoft Skype for Business Server 2019 or Skype for Business Server 2015 environment, consider the following scenarios after you configure User A for Location-Based Routing (LBR):
Scenario 1:
- User A signs out of all clients.
- User B makes an inbound PSTN call to User A.
Scenario 2:
- User A sets up call forwarding to send all calls to voice mail.
- User A then signs out of all clients.
Scenario 3:
- User A sets up call forwarding to an external mobile phone number.
- User A then signs out of all clients.
In all scenarios, an inbound call will hear a fast busy. The caller isn't routed to voice mail or not forwarded to the external number.
