Possible to use Obi as analog to VOIP bridge without other hardware?
GnatGoSplat:
Azrobert, I could use your brain again.
Obi110 doesn't work with GV any more, but what I had with using my Obi200 to forward GV calls to the 110 works fine for incoming calls. However, I can no longer make outgoing calls using GV. Is it possible to forward outgoing calls through the Obi200 without affecting how the Obi200 works with the phones currently connected to it?
azrobert:
OBi200
Voice Services -> OBiTalk Service -> InboundCallRoute:
{200222222>(Msp1):sp1},{ph}
Replace 200222222 with the OBi number of the OBi110
OBi110
Physical Interfaces -> Phone Port -> OutboundCallRoute:
The 1st rule is: {([1-9]x?*(Msp1)):pp}
Change it to: {(<510111111*>(Msp1)):pp}
Replace 510111111 with OBi number of the OBi200
Any number dialed on the OBi110 that matches the SP1 digit map will be prefixed with "510111111*" and routed to the OBiTalk network.
This will send the call to the OBi200 where it will be routed to SP1.
azrobert:
I forgot about the IP phone.
OBi110
Voice Services -> SP2 Service -> X_InboundCallRoute:
{line1:li},{line2>(<510111111*>(xx.)):pp}
Edit:
All the above requires the OBiTalk network to be functioning.
You could change the IP phone to send line2 calls directly to the OBi200.
OBi110 outbound calls could be routed directly to the OBi200 over the local network.
You would have to define a dummy SIP trunk on the OBi200, like you did on the OBi110.

Thanks azrobert!
I don't have anything plugged into the FXS port of the Obi110 and probably won't use it, I'm just using its FXO port to connect PSTN to the IP phone line 1.
So maybe your suggestion to change the IP phone to send line 2 calls directly to the OBi200 and bypass the OBi110 for line 2 entirely is a more direct way to go. I'm guessing I just need to configure my router to port forward the correct ports to the OBi200 and define the dummy SIP trunk.
I'll play around with that and see if I can make any magic happen.

I had this working great on my home network with GXV3275 IP phone, Obi110, and Obi200 connected to the same network. I used Obi110 as the SIP-to-landline gateway for line 1, and Obi200 as SIP-to-GV gateway for line 2.
Now I have taken the phone and Obi110 to my workplace, where they are behind NAT. The phone and Obi110 can communicate directly so no issues there, I just had to reconfigure their new IP addresses. I have the SIP port range 5060-5063 forwarded at home and also forwarded at work. I have set both devices to communicate with the public IP addresses. I can make outgoing calls, but there is no sound, so seems like RTP not working. Incoming calls don't work at all. The Obi200's ITSP RTP defaults to ports 17100-17198, so I'm port forwarding those on both ends. Phone has a "local RTP port: 5004", so I'm port forwarding that at work. Still not working. I think it has something to do with needing NAT translation. I don't have a STUN server. Any ideas on how to make this work?
Would going through the Obitalk network be the only solution? I'd prefer to reduce lag by having the phone communicate as directly with the Obi200 as possible so that's why I was hoping there might be a solution outside of Obitalk.
