Can I connect my Linksys SPA2102 to a POTS line?

I have a Linksys SPA2102 that i got for super cheap (Definitely less then 2 euro from the thrift store, maybe 95 cents.) and I want to use it as an interface for Asterisk so Asterisk can communicate with the outside world/POTS telephone system. Is it possible to do this, or do I have to buy a LinkSys PAP2T as some other thread suggests? (Integrating with POTS line)

According to Linksys SPA-2102 Analog Telephone Adaptor the PAP2T isn’t suitable either. You need one that supports FXO, Of those listed, it would have to be SPA 3102 or SPA 400.

What does FXO mean? What other hardware is used among the Asterisk community that has FXO if you know?

Foreign exchange office, as against Foreign exchange station. Which is basically exchange versus phone, or superior exchange versus PABX.

FXO interfaces sink ringing current, and DC power from the line, and request line seizes. FXS interfaces source ringing current, and DC power to the line, and detect line seizes.

An Obitalk 110 will also provide FXO and works well with Asterisk. It is past EOL but you can still find them for sale.

Is there are list of FXO’s that work well with Asterisk?

I imagine a list of FXO SIP gateways that don’t would be a lot smaller.

Is there a “budget” FXO gateway? They all seem extremely expensive.

You can get a used Obitalk 110 for less than $50 on eBay.

The Grandstream HT813 is one that comes to mind. You can find them for around $50-$60 on the lower end. 1 FXO port, 1 FXS port.
