The formatting of your configuration is mangled so I'm not sure exactly what it looks like (always post Filebeat configuration formatted as code), but it seems to be this:
filebeat:
prospectors:
-
paths:
- "/home/syslog/filebeat/redware/*.log"
document_type: syslog
paths:
- "/home/voip/cdr_StandAloneCluster_01_2016*"
document_type: cucm-cdr
If that's the case then you're missing a "-" before the second "paths" declaration. See the example at https://www.elastic.co/guide/en/beats/filebeat/current/configuration-filebeat-options.html.
