No sound on External Devices - Beginner Help

Howdy partners,
I’ve mange to install and configure VitalPBX on a VM a using my ISP Router to forward the needed ports to use with the Public IP Address.

Forgot about this. Thank you guys for being helpful! the video above me would sure be useful for future setups. If I remember correctly it was indeed PJSIP Port forwarding. Amazing software, looking forward to see it grow.
