Weird Telus Network Issue

I am having a very strange problem ever since I ported over to TELUS where my wife is unable to call me. I was with Koodo before and never had any problems.

Background: My wife is with Koodo using an iPhone 6S. I am with Telus using an iPhone 11. Our phone numbers are very similar and only off by 2 digits.

Problem: When my wife’s iPhone is connected to VoLTE and she calls me she immediately gets a popup, “User Busy”. On my end, my phone rings and when I answer it immediately disconnects. My wife is able to call other people without issue, only calling me results in this problem. Other people can call my phone without issue as well. This only happens when my wife calls me. I can also call her without issue.

Troubleshooting: Manually switching my wife’s phone to use 3G for calls fixes the problem and she is able to call me without issue. Switching both our SIM cards to brand new iPhones results in the same problem. I tried calling Telus and aside from “reset your network” they seem pretty lost about that to do. I have a callback scheduled after they speak to their back office during the week.

Has anyone ever had this issue before? Any ideas on if this is a TELUS or Koodo issue?
