I just realized the code you have routing OBi numbers to the Auto Attendant is in the wrong place. This code should be in the OBiTalk inbound route.
This is what the SPx X_InboundCallRoute should be:
{ph1,pp(290111111)}
If you want to make outbound calls from OBion, you don't need the AA.
Voice Services -> OBiTalk Service -> InboundCallRoute:
{290111111>0:ph},{290111111>(Msp1):sp1},{ph}
Dial the following from OBion:
0 to ring the phone port#1 on the OBi202
18005551212 to route a call out SP1
If you have other requirements, post them.
This code must be placed in the OBion's Gateway OBi202.
If the 2nd OBion doesn't have a Gateway OBI202, you have to dial differently.
