When ECH has been installed via the cmsadm --- install package option. The call record data is no longer collected and stored in the local Informix database, hense no data in the call_rec table.
Rather the now External Call History data is collected and stored as binary data files in the /cms/cmstables directory, these files are prefixed chr and are frequently closed and a new file opened, so you will get many per day. The collected files are either expected to be sent via a serial uucp connection or if the Avaya PSO ech scripts are installed by FTP to another system for decoding and processing into a non Avaya provided database. As they are binary data files they cannot be opened as a ASCII file, they must be decoded first.
There is no provision for both internal and ECH call records to be collected at the same time. It should also be noted that internal call records when enabled can only process 400 call records in a twenty minute period, any more records that have not been complete will be ignored. ECH does not have this limit.
Hope this helps
