Voice Gateways and Session Border Controllers

Question Image

Refer to the exhibit. What is the outcome of applying these two rules to a voice translation profile used with an ISDN T1 PRI on a Cisco Voice Gateway?

  • A The leading Plus is stripped from the numeric phone number
  • B The ISDN Type is modified to the administrator's defined value
  • C Any zero is stripped from the numeric phone number
  • D The ISDN Plan is modified to the administrators defined value
Explanation

Cisco IOS voice translation rules use the type match-type replace-type syntax. type any subscriber accepts any incoming ISDN number type and translates it to the subscriber type. The \0 replacement retains the entire matched number, so the digits are not stripped, and no numbering-plan translation is configured.
