I was curious if I could set a routing so that if I dialed my GV number that is associated with SP1, that rather than going to PH, it would connect me to LINE and allow me to make a call over POTS? Basically, I want it to dump me into the LINE dialtone so that I can then call out on POTS.
I found my problem. I was using aa for inbound calling, and setting aa line to PSTN. However, I did not realize I needed to reboot the Obi in order for the changes to take. After reboot, I am able to call into my GV number and then dial out a selected number on the POTS line connected to the Obi212. Neat!
