Is it possible to purchase a certain "digital module" for an analog PBX?

Question

Telephony

Hello.
On board analog PBX Panasonic KX-TEM824RU
I want CTI-integration, but analog ATS can not do this. Maybe you can buy some kind of digitizing module, which I fantasized myself now? Google is silent ..
Or maybe there is where to put up for sale? Is there a flea market for IT people etc?

I believe that as such, you can, by showing your imagination, connect a SIP FXO border to 8 analog lines. Well, in a perverted way with the configuration of the station.
Although, in my opinion, it is better to get rid of it and implement a sane VoIP solution.
Most likely, the system unit with Asterisk will be the cheapest.
Of course, you will have to change phones or buy gateways for old FXS. (Three eight-port gateways in the aftermarket, that's not a waste at all...)
