Explanation

The default VoIP dial peer (dial-peer 0) in Cisco IOS is an implicit, always-present dial peer that matches any inbound VoIP call that no other dial peer matches. Key characteristics: (B) Fax-rate service is supported - the default dial peer allows fax pass-through at the negotiated rate. (D) RSVP (Resource Reservation Protocol) is not supported on the default dial peer - RSVP must be explicitly configured on a numbered dial peer. VAD (Voice Activity Detection) is actually ENABLED by default on VoIP dial peers, so A is false. The default dial peer supports multiple codecs (not just G.711), making C false. DTMF relay is NOT configured on the default dial peer by default, making E false.
