D53G-5HacD2HnD Hangs up call to multi-sim

Hi, I have a problem with my network configuration.. where I can’t answer calls on my multi-sim that I share with the router

Situation is as follows

  • My router has the real SIM card


  • My phone is running of an eSIM meant to be used by an Apple Watch.

When somebody calls:

  • Router gets a call
  • Cancels call in ~0.1 seconds
  • Phone gets a call
  • Has no time to be picked up

Is there a way for the router to let the call just ring until I pick it up from my phone (even if that means the internet stops working altogether)

Hope someone can help me..

Thanks!
