Explanation

Configuring H.323 call survivability requires three commands in sequence: (A) 'voice service voip' enters the global VoIP service configuration mode; (C) 'h323' enters the H.323 sub-mode under voice service voip; and (D) 'call-preserve' enables the H.323 call preservation feature, which maintains active calls during WAN failures. Option B ('telephony-service') is used for Cisco Unified CME configuration, not H.323 survivability. Option E ('call-router h323-annexg') relates to H.323 Annex G border element routing, not survivability. Option F ('transfer-system') is a CME command for configuring call transfer behavior.
