restricting length of outgoing calls

[tywodllwyd]

I recently received a very high call charge in my Sky bill.  It related to a single outgoing phone call that it says lasted 5 hrs 7 mins 18 secs  (our normal calls are less than 1 hr therefore charged at £0.00).    The actual call lasted 7 mins 18 secs, but it would appear that the call remained open for a further 5 hours, perhaps due to someone not putting the receiver down properly to end the call.     Sky helpdesk were unable to help (or refund the obvious error).   Is there anywhere that I can set the maximum duration of an outgoing call to force an end to the call to prevent this happening again?

I don't think there is I'm afraid as it is up to the customer to make sure the call is ended correctly.
