Question 2

A video device registered with Cisco UCM failed to make an outbound B2B call. From Expressway-C diagnostic logs, an engineer found that the destination pattern is ''john@example.com:5061'', and the call was dropped with a 404 response code from Expressway-C. The search rule intended for this call-in Expressway-C is configured for Alias Pattern Match, Pattern type ''Suffix,'' and Pattern ''example.com''. How must the configuration be changed to allow the call?
