Attended transfer call recording

Hi all

I am able to do attended transfer using *2 feature in

A calls B then B calls C using *2 feature then B hangs and A & C connects.
I enabled call recording for all extensions. I am able to record conversations between A & B as well as B & C but
when B hangs all recording stops.I think there is a way to enable recording between A & C too.
Please help me to solve this issue.I can see that when B hans then MixMonitor stops recording.
Is there any way to enable this???please help me
