The best (FSVO "best") on-call compensation I had was a fixed sum per standby week, for simply carrying the pager. Then, on top of that, overtime at the going rate (150%, 200%, or 300% of hourly rate) depending on when teh call-out happened, with a minimum 3h compensation for any calendar day in which a callout happened (it used to be 3h per incident, until someone had 12 call-outs that each took about 5 minutes to fix).

For partial on-call weeks, the standby comp was adjusted. For good or bad, it was a literal pager, so we could easily adjust things within the team and file paperwork afterwards, as the NOC just called the pager. The downside of that was that it required being in physical presence to hand the pager over.
