Call Log not registering Call Correctly for IAX2 users

Asterisk Call Log not registering Call Correctly for IAX2 users

I have default installation of AsteriskNOW and I add 2 users with SIP and IAX. I try to use Soft phone like KIAX and Zoiper (IAX) and when I call form one user to the other just after a call is established I see record like:

“”,“20001”,“20002”,“numberplan-custom-1”,""“20001"” <20001>",“IAX2/20001-5”,“IAX2/20002-6”,“Dial”,“SIP/20002&IAX2/20002”,“2008-09-08 15:59:52”,“2008-09-08 15:59:56”,“2008-09-08 16:00:08”,16,12,“ANSWERED”,“DOCUMENTATION”,“1220889592.243”,""

This should be useful for billing, but the record was written and call is still in progress - two parties are talking…
After a call is finished no new call record is created.
I think that the record should be created after call is finished with the information haw long call was not just after answering…

I noticed that for SIP clients (like X-Lite) it is working correctly.

All I have it is default configuration of AsteriskNOW.
