CDRLog is a Microsoft Windows service that accepts CDR records in real time from a Grandstream UCM IP-PBX (host is defined in CDR > API Configuration > CDR Real-time Output Settings).

Why?  Because the CDR exports of UCM are not properly formatted when apostrophes and quotes are involved, your data winds up being in the wrong column(s).

Incoming logs are saved to CSV file, Access Database, or SQL Database.  The service can also be queried by Telnet session and HTTP.

CDRLog is compatible with Windows 7, 8, 8.1 & 10

All error logging is done through Event Viewer.
