5 ringing phones- Can OBi202 ring all of them?

[Locquatious]

We have 5 sets of phones at home. 3 are old princess types and 2 are radio phones. If a call comes in, can the OBI202 ring them all at once? In other words I want to unplug from the current provider at the service entrance and plug into the OBI202.

There were many versions of the "Princess". https://en.wikipedia.org/wiki/Princess_telephone

You may not be aware that you can only make calls from an OBi using Touch-Tone dialling.  Rotary dial phones are not supported for initiating calls.

OBis are specced as being able to drive up to 5 REN.   https://en.wikipedia.org/wiki/Ringer_equivalence_number. Old phones usually have a REN of 1.
Newer phones can be significantly less. If your two radio phones are DECT handsets working from a single common base station it is only the base station that the OBi drives and those base stations invariably have REN much lower than 1.

So I would expect that a 202 can be connected to house wiring that has all your phones on it.

Before connecting a PHONE port on any Obi to house wiring ensure that any other phone service wiring is properly physically disconnected.  Many posters here have found out the hard way that failure to do so runs a high risk of causing irreparable damage to an OBi which is outside the scope of the warranty.

I created a post elsewhere for EXACTLY for this situation, and you can use an Grandstream HT802 with 2 ports (instead of HT801 with a single port)  and have BOTH ports connect to the Obi and Google voice! You could still ring probably a single princess on the obi port , so really with an HT802 you get three phone ports total!

I wrote that so PM me on that other forum if you like or need additional guidance.

The issue with many mechanical ringers is lower voltage used for ring voltage on ATAs. Also there are issues with waveform (not sinewave), as well as limited power. So take the  "REN 5 " Statement posted here with a grain off salt. It may provide that much CURRENT, but at what voltage and waveform
