This is driving me crazy. I recently added a GV account into my Obi202 device. I want Line 1 to ring only unless it's in use then line 2 will ring.
I use this setting as instructed to me before:
Voice Services -> SP1 Service
InboundCallRoute: ph
CallForwardOnBusyEnable: checked
CallForwardOnBusyNumber: ph2
The crazy thing is whenever I hit submit CallForwardOnBusyEnable and CallForwardOnBusyNumber go back to obitalk settings. I'm going crazy. Somehow the settings won't save! I even tried to upgrade the firmware but no luck. Please help.
