Microsoft Teams disconnects my cellphone calls

I use Jabra Evolve2 65 with my cellphone and laptop (which has teams).
The issue is that whenever I have a call in my cellphone, and a Teams meeting starts, the cell call is disconnected automatically, and I get transferred to the Teams meeting. Very annoying and not polite, because the other side thinks I hung up on him in the middle of sentence.

Is there any way to setup Teams NOT to disconnect my calls?
