[Freeswitch-users] T.38 with Re-INVITE question

I was testing T.38 with Re-INVITE.

Call Flow:  Inbound Carrier (1.2.3.4) -> FS (Bypass Media) -> Outbound
Carrier that will send T.38 Re-INVITE (6.7.8.9).

However, I noticed that FS generated 2 CDRs for the same call, which are:
1) A-leg CDR from inbound carrier, and also 2) A-leg CDR from outbound
carrier that send T.38 Re-INVITE.

I am wondering whether this is a normal behavior, or there is a way to
ignore the 2nd CDR?


Example of 2 FS CDRs below:


1 : caller_id_name                      = +16193301897
2 : caller_id_number                    = +16193301897
3 : aniii                               = 0
4 : destination_number                  = +12133456789
5 : context                             = routing
6 : start_stamp                         = 2012-09-13 21:12:13
7 : answer_stamp                        = 2012-09-13 21:12:13
8 : end_stamp                           = 2012-09-13 21:14:06
9 : duration                            = 113
10: billsec                             = 113
11: hangup_cause                        = NORMAL_CLEARING
12: channel_name                        = sofia/fs/+16193301897 at 1.2.3.4:5060
13: bridge_channel                      =
14: network_addr                        = 1.2.3.4
15: remote_ip_last_arg                  = sofia/fs/2133456789 at 6.7.8.9
16: bleg_network_addr                   = 6.7.8.9
17: sip_hangup_disposition              = recv_bye
18: endpoint_disposition                = ANSWER
