Connecting to OOMA box

[rnutter]

Before I jump in to setting up a SIP connection, I would like to connect my 3CX system to the OOMA box I am currently using.
Since I plug an analog phone into that box to get service, I am assuming that it is a FXS port.

To connect to OOMA box from 3CX (since a native SIP connection to OOMA isnt an option), the question I have is what type of port to I connect to the OOMA box with?
Since I am assuming the OOMA box is using a FXS port, would I need something like the Grandsteam HT813 since it has a FXO port on it to connect to the OOMA box?
Figured that a FXS port wouldnt be able to connect to another FXS port that I would need to use a FXO port instead.

Will appreciate any suggestions or corrections to my assumptions.

Do not attempt that. Ooma is a cheap option for entry-level.

You want an FXS ATA for your analog phone, but you can't connect to it via the 3CX and have it work perfectly since the Ooma does other things and cannot talk to the 3CX other than analog.

Basically, get a real phone system or stick to your Ooma.

Yes, you would require an FXO gateway, to connect to the FXS socket on the Ooma, in the same manner as connecting a PSTN line to 3CX. If you do a search, you will find a number of posts on the HT813, in the forum. It hasn't been smooth sailing for all that have tried it.

Thanks for your reply and information. I didnt expect this would be easy. Just want to see if I can get it to work. Using this as a learning exercise.

Thanks for your reply. I am aware of issues on the backend of ooma. Looking at this as learning another way of connecting 3CX.

Yeah, like @leejor said, it's extremely tricky to work with this kind of "fake phone system".
