If IP phones are failed over to a backup server and the primary comes back online, will calls in progress be impacted as the phones switch back over to the primary?
No, the algorithm for the fallback will be executed after active calls are finished.
They just silently re-home, no need to do a manual reboot.
Is re-activating a primary server something that can be done during normal business hours usually.
This will depend on many factors, (Number of IP Phones, if remote locations involved WAN bandwitdh, etc) I would recommend it do it after hours in order to avoid high CPU, lack of resources, bottlenecks...etc.
