No CDR when do attened transfer

[nattha]

Hello

I've just installed latest freeswitch version on the Debain11. Scenario test for attended transfer is

1. Ext.A call to Ext.B
2. Ext.B make attended transfer to Ext.C
3. When Ext.B hang up, Ext.A can talk to Ext.C

The CDR show only
Ext. Caller Name Caller Number Caller Destination Destination
Ext.C att_xfer Ext.C Ext.C Ext.A

No CDR and recording file between Ext.B and Ext.C Is it the limitation of Freeswitch or Debain version? Or it's the bug?

Best regards
