I believe there is an error in draft-ietf-stir-oob-07, here in section 9 it
is said that call originates for destination 2.222.555.2222
but then 2.222.222.2222 appears in places I highlighted:

9 <https://tools.ietf.org/html/draft-ietf-stir-oob-07#section-9>.
Example HTTPS Interface to the CPS
(...)
   Assume that an authentication service has created the following
   PASSporT for a call to the telephone number 2.222.555.2222

(...)
   Through some discovery mechanism (see Section 10
<https://tools.ietf.org/html/draft-ietf-stir-oob-07#section-10>), the
authentication
   service discovers the network location of a web service that acts as
   the CPS for 2.222.555.2222.

(...)
   Having concluded the numbered steps in Section 8.1
<https://tools.ietf.org/html/draft-ietf-stir-oob-07#section-8.1>,
including
   acquiring any token (per Section 6.1
<https://tools.ietf.org/html/draft-ietf-stir-oob-07#section-6.1>)
needed to store the PASSporT at
   the CPS, the authentication service then stores the encrypted
   PASSporT:


Rescorla & Peterson    Expires September 10, 2020              [Page 20]

------------------------------

  <https://tools.ietf.org/html/draft-ietf-stir-oob-07#page-21>Internet-Draft
             STIR Out-of-Band                  March 2020


      POST /cps/2.222.555.2222/ppts HTTP/1.1
      Host: cps.example.com
(...)

   The web service assigns a new location for this encrypted PASSporT in
   the collection, returning a 201 OK with the location of
   /cps/2.222.222.2222/ppts/ppt1.

^^^^^^^^^^^^^^^^^^^^^^

->>>>>>>>>>>>> should be /cps/2.222.555.2222/ppts/ppt1



Now the authentication service can
   place the call, which may be signaled by various protocols.  Once the
   call arrives at the terminating side, a verification service contacts
   its CPS to ask for the set of incoming calls for its telephone number
   (2.222.222.2222).

^^^^^^^^^^^^^^^^^^^^^^^^^^^

->>>>>>>>>>>>> should be 2.222.555.2222

GET /cps/2.222.555.2222/ppts Host: cps.example.com This returns to the
verification service a list of the PASSporTs currently in the collection,
which currently consists of only /cps/2.222.222.2222/ppts/ppt1.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

->>>>>>>>>>>>> should be /cps/2.222.555.2222/ppts/ppt1


  The verification service then sends a
   new GET for /cps/2.222.555.2222/ppts/ppt1/ which yields:

(...)
