Openvox voxstack vs-gw1202-8g and NAT by router ECI B-FOCuS O-4G2PWM

Hello,
what should I do for connect from SIP software to Openvox voxstack vs-gw1202-8g?
I can do it only in my home network, but what should I do from Internet?
Do you have instructions? Is this problem with ports?
*.111 - is router
*.1 - is gsm gateway

Hi,
Do you mean connect them at public ip?

you can contact my skype:dario.hu2 and prepare teamview for remote check.
