How to control channel apart from dialplan

Hi,

I have a situation where user logs into my box and does only IVR operations like listen, record to files. He would have a validity for n mins, before he is left with 1 min, I have to take him to another context where he can recharge and continue.

All my IVR operation are done with help of extension.conf dialplans.

Kindly help.

Thanks,
Marutha

However, you can set a time limit on a call, so you can probably do it with the dial plan.
