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?
The command needed must modify the Diversion header in the SIP INVITE to add a prefix to the existing 4-digit directory number, converting it to a 10-digit number. Option B correctly uses a SIP header modification command that matches any digit sequence (represented by the ellipsis) and appends the necessary prefix to ensure the Diversion header conforms to the 10-digit requirement.
There is a Typo with this question! The three answers are the same.
A. voice class sip-profiles 105 request INVITE sip-header Diversion modify “<sip:1(...)@” “<sip:263411\1@” B. voice class sip-profiles 105 request INVITE sip-header Diversion modify “<sip:(...)@” “<sip:263411\1@” C. voice class sip-profiles 105 request INVITE sip-header Diversion add “<sip:(...)@” “<sip:263411\1@” D. voice class sip-profiles 105 request INVITE sip-header Diversion modify “<sip:1(...)@” “<sip:263411\2@” Its B.
why B? both A and B "generate" 9 digit diversion diversion-header sip-user...
A is incorrect because it will only match extensions 1000 - 1999, not ALL extensions.
Jonathanm has the actual correct ABCD answers and A. is the correct answer of those options voice class sip-profiles 105 request INVITE sip-header Diversion modify “<sip:1(...)@” “<sip:263411\1@”
Impossible to answer because of obvious typos
