I just ordered an xlink bluetooth interface that allows you to interface your cellphone to an POTS capable device. Planning on using this with an 820d2. (Before I get grief about using a classic merlin system: I know its old technology but it does everything I need it to do for a home setting and I have a special place in my heart for Classic Merlin sytems)

Anyways plan is to hook it up to an available line port on the KSU. I have not received it yet, but while reading the manual online I noticed that it generates a distinctive ring depending on which cell phone (it can accomidate up to three) the call is coming in on. My question is, will the KSU still ring the extension set normally despite the distinctive ringing voltage generated.

Thanks!
