Call echotest, I don't hear anything

Hi everyone, I’m configuring my first FreePBX server with asterisk as a beginner for a small call center for my business.

I configured everything, created a personal extension and connected it to my PC with Zoiper5. However, when I make an echotest call with *43 I hear absolutely nothing. The call comes through, but I can’t hear anything. What can it be?
this is my pjsip logs

Solved by opening 10000-20000 ports
