Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 34
An administrator troubleshoots call failure in a new deployment and finds that the SIP INVITE messages sent to the service provider contain a diversion header with the user's 4-cigit directory number. These 4-digit directory numbers range from 1000 to 9899. The service provider is rejecting the calls because it requires that the diversion header contain 10 digits. Which command on the Cisco Unified Border Element resolves this issue for all users?
Answer options
- A. voice class sip-profiles 105 request INVITE sip-header Diversion modify ““B.voice class sip-profiles 105 request INVITE sip-header Diversion modify ““C.voice class sip-profiles 105 request INVITE sip-header Diversion add ““D.voice class sip-profiles 105 request INVITE sip-header Diversion modify ““
- B. voice class sip-profiles 105 request INVITE sip-header Diversion modify ““
- C. voice class sip-profiles 105 request INVITE sip-header Diversion add ““D.voice class sip-profiles 105 request INVITE sip-header Diversion modify ““
- D. voice class sip-profiles 105 request INVITE sip-header Diversion modify ““
Correct answer: B
Explanation
The correct answer is B because it modifies the diversion header to meet the service provider's requirements for a 10-digit format. Options A and D are similar but do not include the necessary modification function. Option C incorrectly suggests adding a header instead of modifying the existing one.
