can you let me know if i am doing the responsive firewall correctly as i see extensions from unknown IP trying to register. The request was blocked which means they can reach the pbx but when i tried with zoiper on iPhone (mobile LTE), i could not even register my extension. I will get an error - "transport failure: no transport left to try (503). the description of responsive firewall mentioned that i will be given a chance to register and if it is successful, my dynamic IP will be granted access. if i can’t reach i am not sure how these attackers are doing it.
