Record Termination Cause


I have a scenario where I need to record audio from Line. I use Record in dialplan, I have a termination of ‘*’ with option ‘t’ like below

exten =>s, n,Record(File,0,60,t)

How can I identify whether the recording has completed because of time has reached 60s or user has pressed ‘*’ ???

May be this is repeat question some where but I was not success in searching…
