Section 7.2 says:

   +-----------+                        +-----------+
   |           |                        |           |
   |  Calling  |                        |  Calling  |
   |           |----------->+           |           |-----------+
   +-----------+ 2xx        |           +-----------+ 2xx       |
                 2xx to TU  |                         2xx to TU |
                            |                                   |
                            |                                   |

It should say:

   BEFORE                               AFTER

   +-----------+                        +-----------+
   |           |                        |           |
   |  Calling  |                        |  Calling  |
   |           |----------->+           |           |-----------+
   +-----------+ 2xx        |           +-----------+ 2xx       |
                 2xx to TU  |                         2xx to TU |
                            |                                   |
                            |                                   |

Notes:

Figures 1 and 2 contain "BEFORE" and "AFTER" labels for their respective state machines. Figure 3 does not contain a "BEFORE" and "AFTER" label. Although it's pretty obvious from the context that the left-side is the "BEFORE" case and the right-side is the "AFTER" case, I believe for consistency (and to make it explicit), Figure 3 should contain "BEFORE" and "AFTER" labels.
