AT&T landline phone refuses calls from my T-Mobile cellular phone

Recently got our AT&T home landline phone service connected; however, my husband and I can not call our home phone with our T-Mobile cell phone.  It's almost like both cell phone numbers are blocked but do not show up as being blocked.  Neither AT&T nor T-Mobile has been able to fix this problem so far. Has anyone else had this issue?

Can others call your AT&T number?  If yes it's a T-Mobile problem if no it's an AT&T problem.

Can you call other AT&T numbers?  What happens when you call?  If you get a message what is it? If you're using 10 digit dialing try 7 and vise versa

Yes, we can call all numbers with our T-Mobile cells. We just can't get
through to our AT&T landline home phone. We always get either a busy signal
or a recording that says the number you have dialed is not in service or you
have dialed the wrong number and to please check the number and dial again.
Well, the home number certainly is in service and we have not dialed the
wrong number. We've tried to dial the 10-digit no. with area code, a 1
before the 10-digit no., and the 7-digit no. with no area code.always get
either a busy signal or that same recording.



We've had our same home phone no. for 11 years. We've changed carriers twice
over these past 11 years to take advantage of better deals. We've had
T-Mobile cells for over a year. Never had a problem calling home from
cells..until now.



I might also add that we switched TV-internet-phone (home) service from
Spectrum to AT&T two weeks ago and were given a temporary home phone no.
until our old no. could be ported by AT&T several days ago. We did not have
a problem calling that temporary no. from our T-M cells when we had
Spectrum. It all began on the same day AT&T ported our old no. and it
became available and activated through AT&T.



Both AT&T and T-Mobile are supposed to be investigating the problem, but so
far neither have been able to tell me why it is happening or what can be
done to correct it. I was just wondering if anyone else has had this issue
and how was it resolved.



Thanks.

Yes, others can call the AT&T phone.  If the problem is with the T-Mobile cells as you say, then why would it coincidentally start at the same time  AT&T ported the number?  We had no problems calling home with T-Mobile cells prior to the changeover from Spectrum to AT&T.

Because all carriers have to build their own routing tables to tell the call how to set up.  This is going to be a T-Mobile routing problem, Spectrum's tables were correct to route it to AT&T and the correct switch at AT&T, T-Mobiles isn't. It's that simple.

Ahhh, that sounds plausible. We'll see if T-Mobile agrees and can resolve this issue.  Thank you so much for your help!

I misstated the following:

Spectrum's tables were correct to route it to AT&T and the correct switch at AT&T, T-Mobiles isn't. It's that simple. 

Should read T-Mobiles routing was correct to Spectrum so that's why it worked, the routing tables are wrong to AT&T and that's why it doesn't.  Sorry, but at least you caught the gist of what I was trying to state.  It wouldn't surprise me if they are still routing the number to Spectrum, it can take a few days for all data bases to get updated.

I am having this issue as well. Did you get it resolved?  If so, could you tell me how?

Read the entire topic, this will be a routing problem and since this topic is 4 years old, can only assume the OP's problem with routing was resolved, therefore it can't be the same issue. If you have more or different information that proves you don't have a routing  issue please open your own topic. Closing this to further posting.
