• Question 187:

  When a call is delivered to a gateway, the calling and called party number must be adapted to the PSTN service requirements of the trunk group. If a call is destined locally, the + sign and the explicit country code must be replaced with a national prefix. For the same city or region, the local area code must be replaced by a local prefix as applicable. Assuming that a Cisco UCM has a SIP trunk to a New York gateway (area code 917), which two combinations of solutions localize the calling and called party for a New York phone user? (Choose two.)

  A. Configure the gateway to translate the calling number and apply it to the dial peer. Combine it with a translation profile for called numbers. ! voice translation-rule 1 rule 1 /^1917/ // rule 2 /^ [+]1917/ // ! voice translation-profile strip+1 translate calling 1 !

  B. Configure two calling party transformation patterns: \+1917.CCCCCC, strip pre-dot, numbering type: subscriber \+!, strip pre-dot, numbering type: national

  C. Configure two called party transformation patterns: \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber \+1.!, strip pre-dot, numbering type: national

  D. Configure the gateway to translate called numbers and apply it to the dial peer. Combine it with a translation profile for calling numbers. ! voice translation-rule 1 rule 1 /^1917!/ // rule 2 /^[+]1917!/ // ! voice translation-profile strip+1 translate called 1 !

  E. Configure two calling party transformation patterns: \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber \+1.!, strip pre-dot, numbering type: national

  Correct Answer: DE

  A. SMTP

  B. ICMP

  C. DNS
