I travel. Currently in southwest Asia. I have full bars and LTE on the local infrastructure. I can call toll free numbers, I can call offices, etc... but when I try to call my family located in the US from my Tmobile device (iPhone 7 Plus) to their Tmobile devices, I get a busy signal. My phone, instead of saying their names, will say "User Busy", with the audible busy tone. So I try to call from a US VOIP service (700 code) and it is the same result, busy signal. I can call using FaceTime Voice, FB MSGR Voice, WhatsApp Voice just fine. Though this data option works, I have to have the voice to voice accessibility.
We have turned off our spam/scam/robo features using the noted #____# format.
We have restarted phones.
How do we fix this?
