I gave up looking on the forums and contacted Obi. Here is what they told me.
Quote1. You can set the settings below by logging to www.obitalk.com
click your OBi
click "OBi Expert Configuration"
To have incoming call from phone on BT for OBi to call out via SP1:
-> Voice Service -> OBiBlueTooth
Set "InboundCallRoute" = SP1(number)
I set my Obi up without the portal but it was basically the same. I went where they told me to go under the Bluetooth settings.
Set "InboundCallRoute" = SP1(enter the number you want to forward to here. You would want to use your obion app number here.)
The "SP1" represents which service provider you want to use to forward the call.
sp1 = Service Provider 1
sp2 = Service Provider 2
pp = Obitalk
They put ob in front of Obi and Obi app numbers in these dial plans so you would want something like this.
pp(ob290123456)
Replace "290123456" with your Obion app number.
If you want to still ring the physical phone at home do it like this.
pp(ob290123456), ph, ph2
The thing that sucks is this receives the call then places a new call and connects the two. What that means is the caller ID will show up as your Obi number or unknown instead of the callers ID. That and I told Obion doesn't run in the background.
