From what I gather then, the answer is no. While I appreciate the speed-dial suggestions, understand that is NOT what my parent is accustomed to doing, like calling the neighbor down the street, the pizza shop, bank, etc. Personally I use a VoIP system (Obihai) that lets me program a default area code... the Obihai then prefixes that area code to any 7-digit number dialed. Works great... don't need speed dial, don't need to think about it... just dial the local number like she always has. That's why I say that if this is promoted as a true alternative to a traditional landline, then 7-digit dialing is a must-have.
You would need to attach a telephone to this module for it to work. It is a cell phone and requires cellular service from the local Verizon network. There is no long distance fee thus if you needed to call 999-999-9999, that is what you would dial on the phone. You could use a cordless phone with this module and use the speed dial built into the phone to dial the numbers for the person without them having to remember any numbers. The system is very simple.

Jim, it's not necessarily a "hardware" issue or one that pertains to the physical phone one is using that determines if 7-digit or 10-digit dialing is used.
The FCC (Federal Communications Commission) and the Local Exchange Carriers determine these things. Until the establishment of area code "overlays," everybody could use 7-digit dialing for local calls within their area code. However, more and more cities are now using area code overlays.
7-digit calling can still be done in some areas but it is mandatory in cities with area code "overlays."
For example, Clark County Nevada - Las Vegas (as a very recent example) has exclusively used the 702 area code going back decades. Everybody that had the 702 area code could use 7-digit dialing to call another 702 number. As the population is expanding, more telephone numbers are going to be needed. So a new area code needed to be introduced in order to create more phone numbers. The traditional way would have been to break off a geographical area and assign it the new area code. This was commonly done years ago when new area codes were needed in a city/metro area. However, recently, they have been using the "overlay" method where they "lay" the new area code "over" or on top of the existing area code. This results in the possibility that your next door neighbor will have a different area code than you do.
So now Clark County Nevada (Las Vegas area) has a new area code of 725 overlayed on top of the current 702 area code. Therefore, it is now mandatory to use 10-digit dialing even though the number you are calling has the same area code as you do. This also applies to smaller towns in the county. For instance, Laughlin Nevada which in in the 702 area code will still have to use 10-digit dialing even when calling their next door neighbor who could have either a 702 or 725 area code in their number. They've always were able to use 7-digit dialing but not any more.
I have friends in Portland and Salt Lake City areas where overlays are used and they also must use 10-digit dialing and there are many many more metro areas where 10-digit dialing is becoming mandatory because of overlays.
With all that being said, I would recommend that your parents program (or you program for them) "speed-dials" where they just push either one or two keys to dial those numbers that they frequently call when or if overlays come to their area code someday ...or that can be done even now with 7-digit dialing as that would make it much more convenient for them. I have done that for my parents. Just about all phones nowadays have the ability to program speed dialing to frequently called numbers. That would eliminate the need to worry about 10-digit dialing when or if it comes to their area.
(I may not be entirely correct in all the details of this explanation as I'm not an expert at any of this and there may be exceptions or something I missed but this is a general explanation as to how it was explained to me.)
