Getting an OBI device to work with a Cisco IP Phone

[Weston02493]

I have an OBI212 working with Google Voice, my POTS landline, and deskphone.  I also have a Cisco IP phone (SPA525G2) that I am trying use with the OBI. I have searched but have not seen any info on configuring the OBI and IP phone to work together. Is it possible? or does it require a PBX in between?

Would appreciate some help getting this set up. I am technical, but telephony is new to me.

Thanks in advance.

There have been several quite extensive threads about Cisco IP phones and OBi ATAs so very surprising you claim to have searched but not found even one.

Try using Google with the following search string.

Start with this.  It is a challenge.
