My estranged aunt is contacting my mother suddenly threatening to kill herself because my brother and I won't talk to her

We haven't spoke in like 15 years. My mom is screaming at me YOU HAVE TO TALK TO HER ON THE PHONE OR SHE IS GOING TO KILL HERSELF.

I told my mom to call the police in the state she lives to check on her. She always does this guilt trip so people are forced to talked to her. I also don't like my mom putting my dads sister death on me.
