Again, did the IP Phone register to the OBi202?
In OBi Expert click Status then System Status.
Under SP2 Service Status if the phone registered it should look something like this:
"Registration Not Required;local_client=192.168.1.21:5060"
If you changed SP2 Service X_InboundCallRoute to "ph" and nothing shows in the Call History then the call is not getting to the OBi202. This configuration works for me, so I don't know what's wrong.
The following has nothing to do with your problem:
QuoteSP1 Service (Google Voice), X_InboundCallRoute: {SP2(Njoror@192.168.1.21:5060;ui=$1)},{ph}
I think the SP1 Inbound route should be:
{SP2(Njoror@192.168.1.21:5060;ui=$1),ph}
Processing move left to right and stops when the call is routed.
The way you had it only the IP Phone will ring.
Rule {ph} will never get executed.
