Voice Gateways and Session Border Controllers

When a call is sent to a gateway, the calling and called party numbers must be adapted to the PSTN service requirements for the trunk group. If a call is locally destined, replace the + sign and explicit country code with a national prefix. For the same city or region, replace the local area code with the applicable local prefix.

Assume that Cisco UCM has a SIP trunk to a New York gateway (area code 917). Which two solution combinations 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
Explanation

Cisco UCM applies calling-party and called-party transformation patterns separately when a call egresses to a gateway. For a local New York number in global form, +1917 plus seven digits must be stripped to produce a subscriber-format number; for other NANP numbers, +1 must be stripped to produce a national-format number. The required called-party patterns are \+1917.XXXXXXX with pre-dot stripping and Subscriber numbering type, plus \+1.! with pre-dot stripping and National numbering type. The same patterns are required as calling-party transformations for the calling number.
