Looks like you are heading towards your own world-wide network of OBi's :D
If numbers are not in the "Trusted Callers" group or there is no Caller ID, then the default DigitMap sends them straight to the attached phone. They cannot get access to the auto attendant.

More questions:
1) What happens if my wife tries to place a call from our OBi (or the app on her smartphone), and she wants to use the POTS line at my step-daughter's house in Romania... but my step-daughter is already on the phone (using the POTS line)? Does the OBi at the step-daughter's house tell my wife that the line is in use?
2) Can the smartphone app be linked to BOTH OBi devices simultaneously? Is there a way to choose, inside the app, which OBi to use when placing a call? The reason I ask is... if we are traveling outside the USA, it would be nice to be able to choose to use the OBi in either country. This would allow us to simply walk into any place that has a WiFi hotspot, and use the phone for free!
3) Let's say that my wife's mother calls my wife's daughter's land line, and she uses the OBi to place a call to us here in the USA. So, now my step-daughter's land line is busy. How does my step-daughter know that her phone line is already in use? I assume that one of the lights on the OBi will indicate this. But, if she doesn't see the lights on the OBi... What happens when she picks up the phone in her apartment? Does she just get a dead line? Does she hear the on-going conversation? Or does the auto-attendant tell her that the line is in use? Can she join the conversation so that she can either talk with both of them or ask them to get off the phone so she can use it?

1. The OBi at daughter’s house will tell your wife “There is no service available to complete your call”.
2. If you have the login details of both OBi’s, then you can log in to either one, but only one at a time. Only one OBiON app can be logged in at a time to one OBi. I’m not sure why you would want this as from a wifi hot spot you can log into your USA OBi and dial through that device or from the USA device onto your daughter’s OBi and use that device. One word of caution – there has been some dissatisfaction expressed on this forum about the OBiON app for smartphones. Have a search around on this forum.
3. The line port light will go from steady to a slow flash. When your daughter picks up the phone she will get OBi dial tone as the OBi does not know which service she wishes to dial out on. Attempting to dial out on the busy landline should get her a fast busy or the “no service” message”. There is a “barge-in” facility set up with a Star Code *96.
I tried the question 3 scenario on my setup and got an error message “No service configured error …”. My setup is quite complex using trunk groups etc, so it might be a glitch caused by that. More testing required by me and then maybe a word with Obihai!

Thank you for your answers. I plan to buy the devices and have them shipped to me in the USA. I'd like to get them configured before shipping one of them to Romania. Of course, that means that I'll need to (temporarily) get a land line for configuring/testing the OBi that will be shipped to Romania. We don't have a home phone right now... everyone in the family (here in the US) has a mobile phone.
Will they both work connected to the same router (with only one public IP)? From what I've read, it sounds like I'll need to forward port 5060 to the OBi. Can I use different port numbers forwarded to each OBi on the same router?
If possible, it sounds like a good idea to use unusual port numbers due to SIP scanners. Is there a place in the obitalk website to configure the port number of each device?
I assume that I'll need to setup two accounts on obitalk.com, and link one OBi to each account?

Obihai recommended ports to open:
http://www.obihai.com/FAQ.html#ports-to-keep-open-on-my-router
I would do any configuring via the ObiTalk Portal - Expert Pages Configuration. This allows a simple way to do remote configuring.
Each Service Provider (sp) has a UserAgentPort. Default for OBi110 is sp1 = 5060, sp2= 5061. To avoid scanners I use more obscure ports in the range 5466 to 5499. This may not be a problem for you as you have not spoken about setting up any Service Providers. So far, what you wish to achieve can be done using the OBiTALK network and landlines. I assume that you will put Google Voice on the USA OBi at some point for free North American calls. This setting controls UserAgentPort (sp2 used as example):
Voice Services -> SP2 Service -> X_UserAgentPort : 5061
There is no problem setting up two OBi devices behind one router. To avoid any confusion, I would give each sp a unique UserAgentPort. Maybe use 5470 and 5471 on first OBi; 5472 and 5473 on second OBi. Port forward those ports if you intend to use those Service Providers.
It may be of interest that one of my landlines is in fact an Xlink BTNN. This allows mobile phones to be used as landlines. The OBi110 sees it as a normal landline. You might want to consider using an OBi202 with Blue Tooth adapter at the USA end.
It is possible to add more than one OBi device to one account. However, you will find it easier to set them up using two separate accounts.
