CDR Records And Conferences

At least in version 12.2.0, the code in cdr.c appears to create CDR
records for each pair of users in a conference. This is quadratic and would seem to be an issue with large conferences.

I got two Asterisk crashes when a lot of people tried to dial into a conference. They appear quite related to

https://issues.asterisk.org/jira/browse/ASTERISK-24758

There are thousands of CDR entries on the chain. I believe this is due to the quadratic behavior above. Not all of the “last” fields point to the same entry, which is peculiar, though.

I think that my crash was caused by a stack overflow in recursive calls to delete the huge CDR chain (over 7,000 entries).

Why are all these CDR entries made?
