Voice Gateways and Session Border Controllers

An administrator must remove the initial 9 from outbound calls on an IOS Voice Gateway while ensuring that 911 emergency calls are handled. Which configuration is required to complete this task?

  • A
  • B
  • C
  • D
Explanation

Emergency dialing must be matched before the general outbound rule so that 911 or 9911 is translated to 911. All other outbound numbers beginning with 9 are handled by matching the leading 9, capturing the remaining digits, and replacing the number with capture group \1, thereby removing only the access digit.
