An unfortunate reality of on call is that companies care about projects delivered, not disasters averted.
Unless your stepping in to right the ship when a company is on fire operationally, and can point to specific action/results you delivered to right the ship - getting pages 8x per week does nothing for your career.
In my own situation, I removed myself from on-call duties during a leave of absence, and never went back on after I returned to work. Since then, I've still gotten the same raises I got before.
