[Freeswitch-users] XML CDR Causes B Leg Hang

[Anthony Minessale]

What is actually happening is the CDR state CS_REPORTING comes after
the channel is hung up.
The session is executing the post in its independent thread and it
will remain in existence until the cdr post is complete.
I think if it fails, it writes it to disk for a backup.
