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?
- A . rule 1 /^/+([^1].*)//0111/
- B . rule 1/^+1([2-9]..[2-9]……$)//1/
- C . rule 1 /^([2-9]..[2-9]……$)//1/
- D . rule 1 /^+1([2-9]..[2-9]……$)///

Why would RTP traffic that is sent from the originating endpoint fail to be received on the far endpoint?
- A . The far end connection data (c=) in the SDP was overwritten by deep packet inspection in the call signaling path.

- C . The RTP traffic is arriving beyond the jitter buffer on the receiving end.
- D . A firewall in the media path is blocking TCP ports 16384-32768.
