A Cisco Unified Communications Manager (CUCM) cluster is configured with a SIP trunk to a Cisco Unified Border Element (CUBE) for PSTN connectivity. Users report that outbound calls to a specific area code fail, but all other calls succeed. The CUCM route pattern for that area code is configured with a route list that includes the SIP trunk. The CUBE shows that it receives the INVITE but rejects it with a 488 Not Acceptable Here. Which CUCM configuration should be checked first to resolve this issue?

A Cisco Unified CM cluster is configured with a SIP trunk to a Cisco Unified Border Element (CUBE). Calls from the PSTN arrive at CUBE and are sent to CUCM.
