hello
i am still facing issues with my grandstream ip pbx when i try to use phones over the internet
i have a public static ip on my xg125 and a forwarding rule for the sip and rtp ( for my internal ip pbx lan )
what can i check other than disabling sip from firewall which i already tried ? i had the same problem with a soft phone app and it is still no resolved
is my rule correct ?
