SIP / VoIP Phone in loud workshop environment.

Just installed a new phone system (Sangoma FreePBX.. it's pretty good). 2 of the Sangoma Phones / extensions are in a loud environment / machine shop. The new phones don't have as loud a ringer as the old phones. No-one can hear them.

There are loud ringers for SIP systems but they're pretty expensive at around £250 / £300 each.

I was thinking using something like this.. VoIP to analogue adapter: https://www.voipon.co.uk/fanvil-g100s-analog-adapter-ata-gateway-p-7924.html

Then this.. a loud ringer for a traditional analogue system: https://www.discountcommunications.co.uk/acatalog/BT-Loud-Indoor-Telephone-Bell-877905-DC9814341.html?gclid=CjwKCAiA8OjjBRB4EiwAMZe6y85yqiDwItHsEmM3O7CzM1osciyxTeiwS9aTrHNDMld_kvqevLcosxoCaiIQAvD_BwE

Then was Gona give the Adapter / Ringer it's own extension.. then set it in a ring group so it rings along with the handset extension

Would this work?
