Which option below is the typical approach to maintain local call processing during WAN outages at remote sites?

Explanation:
Survivable Remote Site Telephony (SRST) is designed to keep basic call processing alive at a remote site when the WAN link to the central call control fails. With SRST enabled on the local router (and phones registering there), the site can continue handling internal calls and make/receive external calls through a local gateway or PSTN, even if the central call manager is unreachable. This minimizes disruption until the WAN (and central system) is restored. DNS SRV is for locating SIP servers, not for survivability. CUBE acts as a border/trunk gateway and doesn’t provide local call processing in an outage at the remote site. Informix SQL is irrelevant to telephony survivability.
