Refer to the exhibit. An engineer deploys this Cisco Unified Border Element configuration, but the phone at extension 2221 does not ring. The following configurations have already been completed in Cisco UCM:

  • phone configuration and registration
  • SIP trunk configuration
  • translation pattern configuration

Which action resolves the issue?

  • A Apply voice translation-rule 3 to dial-peer 11 voip.
  • B Change the destination pattern for dial-peer voice 10 to 2... $.
  • C Apply voice translation-rule 3 to dial-peer 10 voip.
  • D Replace voice translation-rule 3 with voice translation-rule 1.
Explanation

The inbound VoIP dial peer must apply the called-number translation that removes the 555555 prefix, converting 5555552221 to extension 2221 before the call is routed to Cisco Unified Communications Manager. An incoming translation profile on the inbound dial peer performs this call-number translation.
