Not really able to help on your question, but why not go with something like this:

with a sip carrier or:

if you really want google voice. Not sure that the second one is still supported.

You can use a ATA box to convert the fax phone signal to VoIP.

This will allow you to connect to a SIP network via static IP or by registration.
I've used ATA boxes to test fax over SIP with my companies software and it worked fine. I've not used the cisco boxes linked above and can't remember the model I used. It supports G711/T.38 either way so should be fine.

An ATA is a device that will register a SIP extension and hand it off to a normal POTS phone.

This way you don't need to replace all your phones.

You will probably need to get a voice gateway.

So you need something like this : Cisco SPA112.

The rest of your plan seems to be really good. It will be a much better network than what it is now.

Get an Analog Telephone Adapter like this - it will present dial tone to your burglar alarm. You can also have it put dial tone on your existing home POTS wiring so your old phones work just like they did before you cut over to voip.ms.

Set up each device that connects to voip.ms with its own subaccount.

The voip.ms wiki has lots of good advice.

The coolest thing about voip.ms is that you can set up a "Caller ID filter" to direct all incoming calls from unknown numbers to a simple IVR like "Press 5 now." If the caller doesn't press 5, they get disconnected. It blocks 100% of robocalls.

I'm in the lower Hudson Valley NY. For my home office I use Callcentric with a Cisco SPA112. Callcentric is based in NY and their quality is excellent.

We use a company called Skyswitch.

They're really good as far as call quality. They've also had no outages in the last 4-5 years we've used them (at least in our area).

We primarily use Cisco SPA 112 as the ATA for residential customers and Polycom VVX 410/411 for businesses.

I have no experience with Google voice though.

Hardware:

• Yealink T46G
  
• Cisco SPA112 (For a couple ATA handoffs around the house)
  
  SIP Software:
  
  
• Linphone
  
  VoIP Server:
  
  
• FreePBX 13
  
• QubePBX - Been playing with it, haven't deployed in production. Very nifty though.
  
  Trunking:
  
  
• Questblue - Best provider I've used both professionally and personally. Highly recommend them.

The product you're looking for does not exist, and if it did exist, it would not work.

The Huawei router you've linked in your replies contains a built-in SIP Gateway. In order to get that feature back after you replace your router with one that doesn't have it, you need to plug something else into your new router to get this feature back.

Any SIP gateway like this Cisco device or this Obihai device will work. They'll still need to be configured to work with your SIP service provider.

You would need an Analog Telephone Adapter (ATA) such as this: https://www.amazon.com/Cisco-SPA112-Port-Phone-Adapter/dp/B00684PN54/ref=sr_1_1?s=electronics&ie=UTF8&qid=1525091775&sr=1-1&keywords=cisco+spa112

It will convert from the IP world of Asterisk to the Analog world of your home phone. Even better would be to port your phone number to a VOIP provider such as Flowroute, Google Voice, etc

For that, you may need to buy a separate phone modem. I believe it depends on which VOIP service you have. If you have comcast, I don't know if they let you use any old voice modem. I use a service called voip.ms, and they let you bring your own device. I have this one, and it works fine for under $30.

If you are going to be at a place where you are hooking up new phone service, you might want to consider other solutions which I hear are extremely easy to set up, and very cheap (basically free plus taxes) such as [Ooma free telephone service]
