OOMA line auto attendant

[kingrocks]

Currently I have google voice configured with Obi110 and OOMA to the LINE Port of the OBi. If Google voice goes away after some days, how to make OOMA as a standalone auto attendant so that I can use my calling card service. is that possible. Ron helped 3 year ago on this . See the below post.
