Wont certain packets follow different routes and then it should take extra time at the receiver end to reorder them?

My school has Cisco IP telephones in all offices. Like the one shown above.

Whats the specialty of IP telephones as compared to the usual telephone at home?

Does the IP telephone operate on the local intranet/ethernet? And the voice is sent as packets?
Hence how can u guarantee about quality as packets might get lost/damaged due to network congestion?
