ObiHai 110 and SIP Door Station (Valcom)
ianobi:
Calling without registration is really not difficult within the same subnet as the OBi. I use it with softphones etc all the time. My post about using an OBi to set up a Home PBX relies mostly on calling without registration.
The problem here is that we do not know exactly how this unit functions. I watched the video and it does imply that the usual way is via an IP PBX which it is registered to. However, I also note that in the SIP setup screen there was a check box for "register", so I guess if left unchecked it does something without registration.
If the OP wishes to go ahead, we can give him some pointers, but he would have to be prepared for a lot of trial and error to reach any conclusion, good or bad.

Do you think the the VIP-172L SIP Door Station (including the Network Interface) could register with a free Asterisk Server such as PBXes.org as an extension and use this third party medium to operate the Intercom via the OBi110? Come to think about it, the DoorBell Fon can be operated through a PBX Server as described here:

I have been looking for a way to get the DoorBell Fon and OBi110 to work without running my own PBX. I'm really interesting in having the ability to speak to anyone at the Front Door from my Mobile Smartphone (3G or WiFi). I noticed an alarming trend where I live, where Burglars always ring your door bell first, to determine if someone is home, before burglarizing your home. This way, I can answer the Intercom whether I'm home or not. Currently my DoorBell Fon is hooked to the OBi110 as shown here (VOIP Wiring Diagram on Page 5):

This setup works fine and it rings the attached phone(s) attached to the OBi110, even call waiting works with the DoorBell Fon, even if I'm already on a call, but cannot figure out a way to send the call from the Intercom offsite.

Google turns up this YouTube video of installing the unit. The video assumes you have an ip PBX like an Asterisk PBX where you register the device as a pbx extension and when you push the button the device calls another extension which is your phone. You make the settings on the device using a downloadable software tool from the manufacturer.

As you know the OBi is not an ip PBX so in order to use the OBi with the device you would either need to use a third party managed PBX where you setup your extensions or you would need to communicate with the OBi using direct ip calling between the units without registration. To do the latter you will need to understand your network and some advanced settings on the OBi unit. The unit also requires a network setup where you provide power to the unit with power over ethernet which means you need to have an ethernet switch or router that will provide that function.

I guess this would work if the VIP-172 and the OBI were both PBXes extensions. If it was me (not likely at that price!!) I would look into direct ip calling first as that keeps it all inside my own subnet and all cabling and services within my own home.
If your DoorBell Fon is ringing the OBi phones, I assume it uses an spX to call in. Or can it simply use the Line Port? Either way I'm guessing you could use the InboundCallRoute to fork the DoorBell Fon calls to your cell phone if it shows up with a unique CallerID. What does Call History show now when the DoorBell Fon calls the OBi?

It looks like your DoorBell Fon rings your PSTN phone which means it would come into the OBi110 Line port. As ianobi said you could fork the incoming call to both your phone and to your Mobile phone. If it doesn't come into the Line port then it would come into the SPx port and the same forking would apply. If you have some caller id coming in on the call from DoorBell Fon you could filter the forking on that, otherwise you could send all calls out to both the phone and the mobile.
One problem that you can encounter doing this is the Mobile phone voicemail (if you have voicemail on it) picking up the call if the Mobile phone is turned off, out of range, or busy. I fork all incoming PSTN Line calls to my mobile phone and I use voip provider Anveo which has a filter you can invoke to keep from answering the call if voicemail answered the call. It works for my mobile provider (T-Mobile). One disadvantage is you have fund the account and to pay a slight pay/go fee using Anveo Call Flow and for the call termination if you answer it on your mobile. I fork the call using a sip uri to my Anveo account where I use Anveo Call Flow to invoke the filter and ring my mobile phone.

The Door Station for the DoorBell Fon (and assume the VIP-172L SIP Door Station) is really dumb component of the system (Speaker & call/push button). It doesn't have any brains by itself and needs the Controller piece to interact with the Phone System. If you look at the manual (page 2 and Page 5), the line leading from the Door Station is connected to a + and - terminal on the Controller and cannot be connected to the LINE port of the OBi110 (or SPA3102 for that matter - I had this setup before purchasing the OBi110). Page 2 of the manual shows the typical setup with a normal PSTN line, while Page 5 shows the setup where you have a VOIP ATA serving as the "PSTN" line. The Controller for the DoorBell Fon and VIP-172L is the brains of the system. In case of the DoorBell Fon, there are two leads connecting the Door Station to the Controller, while the VIP-172L uses a RJ45 (LAN) cable between the Door Station and the Network Interface Box (Controller).
Currently, when someone at the door presses the Call Button, there is no caller ID that shows up on the Phone LCD screens, so there is nothing that can be use for forking a "call", nor is it "forkable" unless it can be intercepted before it goes out to the phone ("To Phones" - see diagram on page 5). The only thing that distinguish the DoorBell Fon "calls" are the distinctive ring pattern.
DoorBell Fon Manufacturer use to make a separate component that could be integrated with the two components of the DoorBell Fon that could be used as a dialer and could dial an outside line, They discontinued that component (Dialer) some years ago for some reason and they claim they are working on replacing it with something else. I'm hoping the new module will have some form of embedded SIP based technology, since I do not wish to replace the entire DoorBell Fon, which only cost $125 at the time I purchased it (going for around $175 now).
FYI: I have Anveo for E911 setup on SP2 of the OBi110 and CallWithUs on VG3.
