[asterisk-users] CDR and call transfer

[Grigoriy Puzankin]

Hello,

I'm using digium E1 cards and serving SIP users at Asterisk. After the 
following call (see below) CDR shows two records. First looks as 
outbound call, but the second - as inbound call. Is it a bug or intended 
behavior?

Call flow:

SIP (ext: 100) -> ZAP (national number)
SIP (ext: 100) transfers to SIP (ext: 200)
SIP (ext: 200) -> ZAP (national number).

In CDR it looks like

SIP (ext: 100) -> ZAP (national number)
ZAP (national number) -> SIP (ext: 200)

How to identify the second CDR as outbound call?

Best regards,
