External Loud Ringer for Digital Phone

[pronei]

I've got a customer who wants an external loud ringer setup with a digital phone.

My idea was to build an analog set connected to the loud bell and tandem it to the digital set.

I've never tried this, in my head it works, but wanted opinions and options before thats what I recommend to the customer.

Hi, on OXE tandem sets must be multiline so you can't use an analogue phone port. Alcatel have relay sets that can be plugged into the phone for this use. Plaese search previos posts on this subject.

Exist UA set external ell interface box 3BD11086ACAA.
Or route calls to analog set. On digital set programm "set supervision key" and for digital set manage in multiline facilities "take supervision at off hook=true"

Perhaps use a remote extension which defines the analog station and place this in tandem with the digital or IP phone
