  A. 33 percent of 1.544 Mb/s
  B. 5 percent of 1.544 Mb/s
  C. 38 percent of 1.544 Mb/s
  D. 62 percent of 1.544 Mb/s
  E. 0 percent of 1.544 Mb/s

• Question 124:

  Refer to the exhibit.

  

  Which number is sent as the caller ID when a user at extension 5001 places a call that matches this translation profile?

  A. 14087775001
