OBi200 is a great little box that let us setup and use Google Voice in a matter of minutes and place/receive calls over the Internet.
Service quality is great and it is free so far.
To make OBi200/OBi202 talk to existing PBX box could be quite a challenge.

Here is how it worked in our case:
1. Setup OBi2xx box with ObiTalk.com to the point of all outgoing and incoming calls work using attached analog phone.
2. Setup OBi2xx / FreePBX on LAN so they can talk to each other.

On OBi2xx Side:
- Download SP2-ITSPB.xml setup file.
After setting up Google Voice on SP1/ITSPA using the ObiTALK Web Portal, disable all Auto Provisioning on the OBi and use:
System Management -> Device Update -> Restore Configuration
import: SP2-ITSPB.xml

Make the following changes:

Service Providers -> ITSP Profile B -> SIP -> ProxyServer : {IP Address of FreePBX server}
Service Providers -> ITSP Profile B -> SIP -> X_AccessList : {IP Address of FreePBX server}



Voice Services -> SP1 Service -> SP1 Service -> X_InboundCallRoute : sp2(8775551212) - replace 8775551212 with your Google Voice number
Voice Services -> SP1 Service -> Calling Features -> MaxSessions : 10



Voice Services -> SP2 Service -> SIP Credentials -> AuthPassword : (password)



On FreePBX/Incredible PBX side:
Create a PJSIP Trunk

General tab -> Trunk Name : obi200
pjsip Settings tab -> General tab -> Username : {Username is trunk name}
pjsip Settings tab -> General tab -> Secret : (password)
pjsip Settings tab -> General tab -> Authentication : Both
pjsip Settings tab -> General tab -> Registration : Receive
pjsip Settings tab -> General tab -> Context : from-pstn-e164-us



pjsip Settings tab -> Advanced tab -> Contact User : obi200



Create an appropriate inbound route and an outbound route pointing to obi200

NOTE:
For some reason, in our case
pjsip Settings tab -> General tab -> Registration : Receive
did not work, so it is set to
pjsip Settings tab -> General tab -> Registration : Send
and all things work just fine although it is not correct setting for registration.


Also, we had to change ProxyServerPort to:
Service Providers -> ITSP Profile B -> SIP -> ProxyServerPort -> 5061
