Refer to the exhibit. An administrator is trying to test outbound calls toward the ITSP but cannot complete the call and receives a SIP error.

  • A. voice class sip-profiles 2
    request INVITE sip-header To modify “sip:(.*)@” sip:8005532447@
  • B. voice translation-rule 3
    rule 1/.*/ /8005532447/
  • C. voice class sip-profiles 1

Selected Answer: B
B is correct A. voice class sip-profiles 2 request INVITE sip-header To modify “sip:(.*)@” sip:8005532447@ Wrong. We need to modify the From header if we want to change the ANI (Calling Number) B. voice translation-rule 3 rule 1/.*/ /8005532447/ Correct. This replaces any digits with 8005532447. If applied to the to the calling number in the correct direction it would modify the ANI C. voice class sip-profiles 1 request INVITE sip-header Diversion modify “sip:(.*)@” “sip:8005532447@” Wrong. We need to modify the From header if we want to change the ANI (Calling Number) D. voice translation-rule 4 rule 1/^.*\(8005532447\)/ /\1/ Wrong. This pattern requires the calling number to be any digits followed by 8005532447 to match, which makes no sense as our ANI is a 4 digit DN
