Currently contracting for a ~10 person company. In the past I've mostly worked at small companies and have never officially been on call. I've fixed the odd out of hours issue here and there without there being a proper arrangement. The systems I work on (trading / betting software) are such that by the time you're through testing it's very rare to hit a game breaking issue because there's a very large incentive to not like, lose the bank. Dependencies in the critical path are kept to a minimum, etc. Usually problems are more 'soft', like an API being turned off or changed or something.
