OBi100 calling direct via LAN to OBi110 gets a busy signal. *SOLVED*

There is a difference between calling the OBi100 directly via speed dial and routing an inbound PSTN call. The latter is called bridging. When you bridge a call with X_SpoofCallerID, you will send the inbound CallerID. That is why your mods didn't work.

Very good point. I should know better as I use a similar setup myself! I recommend:
OBi110 -> LINE Port -> InboundCallRoute: {ph,sp1(201@192.168.1.100:5070)}
OBi100 -> Voice Services -> SP1 Service -> X_InboundCallRoute: {>(201):ph}
This accepts any CallerID, but the callee must be 201. For added security you could change every instance of 201 in your setup and speed dial to a much more complex number that scanners will not likely guess.

For more added security change the UserAgentPorts in both OBi devices to numbers higher than 30000. Be careful to change all instances where that number is used.

Do what azrobert advices first to prove that all functions work as required. Then add my suggestions one at a time.

If any of you have wondered where I've been, I just needed a break from the forum. You probably won't see me again for awhile.

Enjoy your break! I suspect a good digit map or call routing problem may tempt you back   :)

Make the following change:
OBi100 -> Voice Services -> SP1 Service -> X_InboundCallRoute: ph

...

I'm not sure if your OBi's are connected to the internet, but when you just have "ph" for the inbound route SIP scanners will be able to ring the OBi100 phone port.  If you are concerned about this, I'll let ianobi show you how to block them.


Thanks for this suggestion, this fixed it. Both phones ring on an incoming call to the PSTN line.

One of the reasons that I prefer OBi ATAs to Cisco or Grandstream is that for most setups they work without opening ports on your firewall. I prefer to keep my VOIP gear behind a hardware firewall with no SIP ports exposed to take care of the "ghost calls" problem.

For PBX type connectivity, my preferred method is to set that stuff up on the provider side, either via OBiTalk, Google Voice, or sub accounts from a provider, such as with VOIP.ms or Simon Telephonics.

With this setup, I am fairly sure that while my folk's network is connected to the Internet, the OBi gear won't actually talk to the Internet because it's on a different IP subnet.  That's the hope anyway :) I will let the connection to the PSTN be handled by whatever they plug into the PSTN port on the OBi110.

Thanks again for all of your help. I sincerely appreciate it :)
