how can I setup a blackberry for oncall?

Our work team is starting a new oncall rotation where we're passing around a blackberry. it's been a long time since I've had a blackberry. I'm totally an android person. an app I really like for android oncall is klaxon. I set it up so if a certain source number or email texts me, my phone turns volumes to max and repeatedly alarms me until I acknowledge it.

this blackberry, if I'm paged, it calls me and texts me. but if I don't hear the call or the one beep from the text (maybe I'm in the bathroom or I sleep a little harder than normal), then I jeopardize my job.

is there a way to setup the blackberry to do the same thing?

this blackberry is a blackberry classic sqc100-3.
