Explanation

In Cisco IOS-based gateways and routers, a dial peer is a configuration construct that defines call routing - it maps called or calling digits to a specific destination or interface for processing. A VoIP dial peer specifically represents a logical voice connection over an IP network. Answer (B) is correct: a VoIP dial peer is a call routing mechanism that matches incoming or outgoing calls based on dialed digits (DNIS) or calling number (ANI) and directs them accordingly (e.g., to a specific IP address or CUCM). Answer (A) is incorrect - dial peers are addressable endpoints by definition. Answer (C) is incorrect - dial peers are logical, not physical connections. Answer (D) is the closest distractor, but 'logical connection for call legs' is too narrow; the key function of a dial peer is routing based on digits, not merely representing a connection.
