custom recording size *92

How long can a person record a recording by a constant recording *92

I have a customer who uses recording in his phone systems for people to leave long recordings.
It could be up to an hour

I set in his IVR a custom destination *92, and it works

My question is

  1. How long can I record

  2. Can I remove the confirm option that when somebody hangs up the phone,
    It should be saved automatically
    now when somebody hangs up the phone the recording will be lost
