Lots of duplicate entries in CDR

Running FreePBX Distro 10.13.66.

Why do I have plenty of duplicates in CDR?
I also have two entries for the same call, but different showing different duration, even though it’s one call.

This is because you are using CDRs and asterisk 13 in freepbx. CDRs in asterisk 13 use local channels. Basically a lot of them will report duplicates. Try to use CEL. Which we are trying to actively improve.

Running Asterisk 11.22.0 by the way.
