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.
