[Freeswitch-users] I don't have the last session variable after crash recovery with track-calls

[Tristan]

Hi,
I have a problem with the freeswitch (FreeSWITCH Version 1.10.1-release-12-f9990221e6~64bit (-release-12-f9990221e6 64bit)) recovery activated with the
track-calls option.
When freeswitch crash and recover, i have the value of the session
variable of the first call of the callflow.
For example this callflow :

There i crash freeswitch with fsctl_crash and the recover session have :
2019-10-18 10:23:38.885653 [CRIT] switch_cpp.cpp:1443 [MONITOR] [CRIT]
RECORDING_ID:1571386828001

Value expected of RECORDING_ID after crash : 1571386828003

How i tested to set the value to force something (and while i don't
crash the value is true in the session (i checked)):
session:setVariable('_OLD_RECORDING_ID','')
other_session:setVariable('_OLD_RECORDING_ID','')
session:execute('export','_OLD_RECORDING_ID='..'')
other_session:execute('export','_OLD_RECORDING_ID='..'')
session:setVariable('_OLD_RECORDING_ID',tostring(old_recording_id))
other_session:setVariable('_OLD_RECORDING_ID',tostring(old_recording_id))
session:execute('export','_OLD_RECORDING_ID='..tostring(old_recording_id))
other_session:execute('export','_OLD_RECORDING_ID='..tostring(old_recording_id))

Thanks,
Tristan
