Resound phone ringer settings help please


Here is the problem I Have, l have the Resound Linux hearing aids, along with the app, I want the ringer too be heard from the IPhone speaker, along with hearing it ring, through the hearing aids, reason being is I misplace the phone quite a bit, and hearing it actually ring would be beneficial to finding where it’s at,
Under the coach, under the bed, outside, in the car etc…I had it set up correct once before, but have had them serviced, and now I’m lost as to how to set it up in settings again,
I’m hoping someone has had the similar thing themselves, or knows how I can get it back to how I can do so again…Thanks in advance
