I work in a high school with students with disabilities. We bought a bluetooth headset for one of our students to take directives without being distracted by other noises around him. But I would like to "call myself" and talk into my phone for him to hear it on the headset. Yes, I know i could pair it with one phone and call it from another. but the problem is in the building we will lose reception. so is there a way for me to talk into my own phone and for the student to hear me through the headset? Any answers here would help greatly. Thank you all !
