OK, so I have finally gotten OBION to dial thru Obi110 to GV using 2*9999999999 and it works great!
Question: how can I make OBION default directly to GV and eliminate *2 prefix from above OBION example?
If you used the OBiTALK Web Portal to configure the OBi110, you should be able to simply dial an 11-digit number and have it go out the OBi's PrimaryLine (presumably SP1).
You can also use 7- and 10-digit dialing from the OBiON App if you make the following change:
Voice Services -> OBiTALK Service -> InboundCallRoute : {290123456>(Msp1):sp1},{290123456:aa},{ph}
where 290123456 is the OBiON App OBiTALK number.
Even better, use
Single-Stage Dialing Through Any OBi Trunk and you will be able to initate calls using any of the services on your OBi110.
