Can You Split Being on Call at the Same Time?

Oncall to be both a symbol and a responsibility. A part of being on call is deciding. I am for the most part in favor of single person being the primary on caller. And if you have a second for extra support, for relieving, for breaks, for you need to go to the grocery store, i also recommend a secondary,. But exactly that, a primary and a secondary, rather than two co primaries and no secondary.
