Calls incoming from the provider are not working through newly set up Cisco Unified Border Element. Provider engineers get the 404 Not Found SIP message. Incoming calls are coming from the provider with called number ''222333444'' and Cisco Unified Communications Manager is expecting the called number to be delivered as ''444333222''. The administrator already verified that the IP address of the Cisco Unified CM is set up correctly and there are no dial peers configured other than those shown in the exhibit. Which action must the administrator take to fix the issue?
Change the destination-pattern on the outgoing dial peer to match ''444333222''.
Set up translation-profile on the incoming dial peer to match incoming traffic.
Create specific matching for ''222333444'' on the incoming dial peer.
Fix the voice translation-rule to match specifically number ''222333444'' and change it to ''444333222''.
Refer to the exhibit.
Users report that outbound PSTN calls from phones registered to Cisco Unified Communications Manager are not completing. The local service provider in North America has a requirement to receive calls in 10-digit format. The Cisco Unified CM sends the calls to the Cisco Unified Border Element router in a globalized E.164 format. There is an outbound dial peer on Cisco Unified Border Element configured to send the calls to the provider. The dial peer has a voice translation profile applied in the correct direction but an incorrect voice translation rule applied, which is shown in the exhibit. Which rule modified DNIS in the format that the provider is expecting?
rule 1 /^/+\([^1].*\)/ /011\1/
rule 1/^\+1\([2-9]..[2-9]......$\)/ /\1/
rule 1 /^\([2-9]..[2-9]......$\)/ /\1/
rule 1 /^\+1\([2-9]..[2-9]......$\)/ /\0/
