Just set up an OBi today. Got GV working, hopefully it will always ring GV incoming calls, but will see, I heard there can be issues there.
Anyhow, want to set up SipGate as backup for receiving inbound calls. It says SipGate registered and it can receive calls, but on answer, I get one way audio path. Don't receive any audio nor DTMF, but can send audio and DTMF to other party.
Using default Obi config. What changes might need to be made to get 2 way audio? Also didn't try any firmware update. How to check current firmware and if need update?
