i thought about this once upon a time when i was on call (which was all summer long for years and years.) in the end it wasnt worth it (to me.) i just relied on the vibrating feature of my phone. put it in a shirt pocket close to the skin.
anyone with something important will leave a message....
When I'm on-call, I'm seriously on-call. There's even a Federal reg that says that if I'm not present in the ED within 30 minutes of the initial attempt to reach me that I could potentially be personally liable for up to $50,000 in fines. That's not to mention more realistic concerns about good patient care. On top of call, I'm the medical director of my department, so the buck stops with me even when others are on-call.
If I get a call, that means I have to pull over, yank off my helmet and a glove, dig out the phone, etc., etc. In practical terms that translates to no riding when I'm on-call. Given the weather this spring in NH I'd really rather not miss any good riding days that present themselves.
