Which statement is true?

The correct answer is C. VolP dial peers use the H 323 signaling protocol by default. In Cisco IOS, VoIP dial peers use H.323 as the default signaling protocol. When you configure a VoIP dial peer without specifying a session protocol, it defaults to H.323 (using the 'session protocol cisco' or the implicit H.323 stack).

Explanation

In Cisco IOS, VoIP dial peers use H.323 as the default signaling protocol. When you configure a VoIP dial peer without specifying a session protocol, it defaults to H.323 (using the 'session protocol cisco' or the implicit H.323 stack). SIP must be explicitly configured with 'session protocol sipv2'. MGCP is a gateway control protocol and is not the default for dial peers. POTS is a separate dial peer type entirely and refers to analog or digital telephony interfaces, not VoIP signaling.
