Would it make sense to have 15 seconds to the first check, then 5 seconds
interval after that? Or is 15 seconds sample rate good enough? There's a higher
risk of false alarms for short sessions, e.g. for a 29 seconds call we'll only
have 1 sample. If it happens to be silent at that point we have a false alarm.
Maybe those cases are so few we don't have to bother.
