Keep speaker on while headset plugged in...

I just purchased and installed the PRO version of SoundAbout on my Galaxy S4.
What I want to do is when I plug in my Retro Telephone handset into the 3.5mm headphone jack, I want to be able to hear the phone ring through it's main speaker. How can I get this to work? Did I purchase the correct app?

Download the latest Beta from here:

1] Then go into SoundAbout and click on "Alert behavior".
2] Click on "Wired Headset behavior"
3] Click on "Ringtones to:"
3] If you want just the phone speaker, click "Phone Speaker only". If you want the ringer in the speaker and the headset, then choose "Phone Speaker and Headset".

I purchased and installed the PRO version. Do you mean I didn't need the PRO and have to download another version?

You need the PRO version. This new Beta just has more PRO options that I think fit your need perfectly.

I download the latest beta and installed it. I can't get the ringer to go out the speaker. I guess I can't use this handset with the phone.

I got it to work. I guess somehow my ringer was turned down all the way and sisn't see it.

Yes, that happens to me sometimes when I am testing.
