Landline caller always gets busy signal when calling me.

My friend calls our T-Mobil Apple Cell phones and always gets a busy signal. (She can call me from her cell phone successfully.)  She is calling from an ATT landline.  She can call other Apple Cell phones (who are not on T-Mobile) from her landline, just not ours. I have checked my phone for call blocking, call forwarding, airplane mode, do not disturb, etc. And it isn't my phone's settings. Any advice?

    I've been having this problem in San Diego  If an AT&T landline calls any of my T-Mobil numbers the caller immediately gets an AT&T recording saying "Call can't be completed, all lines busy, try again later" I know it's been going on for at least a week for my T-Mobil lines. I tried multiple times to report this to AT&T repair who finally called me back and said it is an AT&T network issue and they "have their tech working on it". They added it is a known network wide problem covering many area codes.  They said it would be multiple days to correct, but reading the messages here it seems more like a long term AT&T issue with no resolution in sight.

     

    As a side note, I tried to report this to T-Mobil thru their tech help number.  The person I talked with  wouldn't take any kind of report or offer any assistance even when I mentioned potentially thousands of T-Mobil customers missing phone calls from their AT&T callers.  Go Figure- where has customer service gone ??

      Yesterday I was finally able to get to T-Mobil technical assistance an talked with a tech who understood the issue.  He took a repair ticket for the issue and escalated the trouble to T-Mobil engineering for diagnosis.  He indicated their engineering department had a method to send the trouble across to AT&T as an AT&T problem.

      I just got a call back from AT&T repair tech with an update.  She said  there is a known ongoing ATT outgoing trunk  system outage to the T-Mobil  cell system.  The trouble is with AT&T and they have multiple reports which have been  "lumped into a general trouble pool".  At this time AT&T has been unable to trace the exact issue and she would only say for some reason all AT&T outgoing trunks to T-Mobil are constantly busy.   She said there is no resolution date.  From what I gathered from the conversation, it appears AT&T possibly has no idea on how to repair or possibly isn't of sufficient concern to AT&T.  

      Go figure, thousands of T-Mobil customers can't be called by AT&T. .  and who really knows how widespread this problem.  I wonder why the TV news doesn't pick up this ongoing story.

    So what do you suggest I tell the landline callers?

    To contact their landline carrier because the calls they are trying to make aren't actually making it to the numbers being called.

    If there was an issue on T-Mobile's end.  It would affect all incoming and outgoing calls to and from a specific provider, not just a few people.  That would also be something that affects a lot of customers as well to the point where a fix would be a high priority.  

  • What if it’s from multiple landlines? Like my son’s school can’t reach me. The doctor’s office can’t reach me. Everyone that calls from a landline phone gets a busy signal. Is there anything I can do?

    It's a routing issue from the end of the landline provider.  They need to complete the call connection being the originator of the call.

    Same thing is happening to me when my dad calls from his old landline.  He gets through fine with his cell phone.  Can’t figure it out.
