Voice Gateways and Session Border Controllers

Question Image

Refer to the exhibit. A translation rule is configured on the voice gateway to translate DNIS. What occurs if the gateway receives 0255-343-1234 as the DNIS?

  • A The translation rule is not matched because DNIS contains ג€-ג€.
  • B The translation rule is not matched because DNIS does not end with a ג€$ג€.
  • C The translation rule is matched and the translated number is 02553431234.
  • D The translation rule is matched and the translated number is 025553431234.
Explanation

Cisco IOS voice translation rules use SED-like match and replacement expressions. The escaped hyphens match the separators, while replacement groups \1, \2, and \3 reproduce the captured digit groups consecutively; the resulting DNIS is 02553431234.
