问题
This is really starting to get annoying.
I´m using Asterisk 1.4 since 2007 to operate a flawless PBX, and it creates a SINGLE CDR per call, like any other version of asterisk would.
Yesterday I figured an upgrade would be ok and got Asterisk 13.4.
This damn thing is creating 2 CDRs per call... one representing the dial attempt .. and another including both the connected call and the initial dial
I don't know where to configure the CDR engine to behave normally... that is, to record A SINGLE CDR per call.. NOT 2!!
Any ideas?
PS: (No, I did not change my code, no I did not config any specific lines out of the ordinary cdr.conf)
Here is the debug output of the CDR engine:

I created the patch for asterisk 13 =) In short, the algorithm of the cdr remained the same, which eliminates various errors. If CDR record is the most latter, then we write it. And the last record is exactly what we need. Tested on version 13.4 and 13.6.
Install: Patch asterisk source code and build/rebuild asterisk.
patch asterisk-13.6.0/main/cdr.c ./asterisk13_cdr.patch
Download: http://miho.org.ua/download/asterisk/asterisk13_cdr_patch.zip
P.S. Write here if this patch help you or if you'll find bugs =)

This is a result of a new CDR engine starting in Asterisk version 12.
Depending on how channels are dialed and bridged, multiple CDRs will be created for a given call. Post-processing of these records will be required to determine the overall statistics of the call.
Before upgrading any software, it's a good idea to read all the upgrade documentation – in this case you've got 7 or 8 years' worth!

I had similar problem.
Asterisk certified/13.8-cert4
One call produced two record. One correct record, second record had the same values except 'start','end','answered' fields, which was empty.
The reason of duplicates record - cdr_odbc.so module.
asterisk -rx "module show like odbc"
Module Description Use Count Status Support Level
cdr_adaptive_odbc.so Adaptive ODBC CDR backend 0 Running core
cdr_odbc.so ODBC CDR Backend 0 Running extended
cel_odbc.so ODBC CEL backend 0 Running core
func_odbc.so ODBC lookups 0 Running core
res_config_odbc.so Realtime ODBC configuration 0 Running core
res_odbc.so ODBC resource 0 Running core
res_odbc_transaction.so ODBC transaction resource 0 Running core
7 modules loaded
I turn him off in modules.conf 'noload => cdr_odbc.so'
Restart server and things is fine.
