--------------------------------------

             Summary: No CDR created after call has been split and then bridged back
                 Key: ASTERISK-20933
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20933
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: CDR/General, Core/Bridging
    Affects Versions: 1.8.19.1, 1.8.15.1, 1.8.14.1
         Environment: CentOS 5 using Digium yum repositories
            Reporter: Alex Barnes


Scenario
===========================

No CDR record is created after a call has been split and then bridged back.  See example dialplan below where a CDR record is created at all points right up to the Bridge command but not after.  Reversing which channel gets bridged still results in no CDR, i.e. the caller doing the bridging or the callee.

In our case the VoiceSafe is acting as an ISDN middle-man to record and log calls before being passed onto the PBX or telco.  I haven't tested purely SIP but I imagine it would be the same outcome.

Note that this was working in 1.8.13 but appears to have been broken in 1.8.14 and above.



Versions
===========================
All packages installed via Yum.

*1.8.13.1-1_centos5 = OK
*1.8.14.1-1_centos5 = No CDR
*1.8.15.1-1_centos5 = No CDR
*1.8.15-0.cert1.1_centos5 = No CDR
*1.8.19.1-1_centos5 = No CDR
