Landline callers get busy signal or Number not in service or Number cannot be reached as dialed

- Member Since: May 10, 2019
I ported my "Landline" over to T-Mobile from OOMA. Despite the issues of getting it ported over properly, it finally did get ported over. I thought all was well and good. This number will act as my "Landline" (aka Home) phone even though it's actually just a cell phone. So we ported it into an Alcatel Flip phone which works just fine.
I thought everything was okay until people started trying to call and would get one of the following:
Busy (sometimes a fast busy)
The number you called cannot be reached as dialed, please check the number and dial again.
The number you called is no longer in service.
All of these are extremely frustrating, especailly when you consider I have not been able to use this phone number effectively for going on 2 months.
I have made NUMEROUS (i.e DOZENS) of calls to 611 to get this resolved. Thing done:
Reboot phone
Reset Network Settings
Swap SIM Card with other device (Problem follows the SIM Card to new device)
Have them re-send Programming (with reboots along the way)
Replace SIM card with a newly (brand new) SIM Card.
Try previous steps (Multiple times)
The phone, although it's a flip phone, I can call any numbers (Landline, Mobiles, IP Phones, etc) that I have tried. Landlines, VOIP Phones, PBXs (that I have been able to try) continues to get one of the above messages. I get text messages, the data works, and I can receive Mobile calls.
After the New SIM Card, it seems like the T-Mobile Landlines (From the Store and while on with the various support under 611) can reach the impacted Mobile number.
I am in Pennsylvania and had my Sister in Colorado try (Clearly a different area code and exchange) and she got the "Number disconnected" message.
I am, truly open to any new things to try. I am currently waiting on the "Engineers" to re-send the the "Programming" over the network (Again). They tell me that it can take anywhere from 2 hours to 24 hours and that they will get back to me after it's done. That's today 5/10/19 at about 5 PM. Of course they said the same thing on 5/7/19 at 6:30PM and I got nothing back (which is why I called again today.)
So any suggestions or ideas would greatly be appreciate.
