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