CDR stopped working: 5.211.65-7 => 5.211.65-19

Following the upgrade, all the way to 5.211.65-19 from 5.211.65-1, new calls are not being added to the CDR. It happened sometime AFTER 5.211.65-6.

Well, that is bizarre.

/etc/odbc.ini now had a single section [MySQL-cel], but as far as I can tell that isn’t the DSN that anything is [currently] looking for. I changed it to [MySQL-asteriskcdrdb] and now not only is the CDR working again but it now appears to be logging CEL data which it’s never done before.
