Did you open ports?

if you did not go through the ports section, then this is the wrong forum to post because it is not an android issue, but an admin / implementation oversight..
Audio ports UDP need to be opened.
And use the latest android client (beta)

all ports were opened as it's on AWS cloud i didn't restrict any ports on that specific server.

but some how i managed it make some rules and other things and it's working now and able to communicate on public network thanks alot for your help as well.

You need to make always port forwarding because networks are not exactly like home networks..
So it is not an android issue - it would have happened using any device..
Happy you solved your issues..

for the record and all the users using aws.. an aws network is different than some other network and this is what makes aws so cool

Between your device and 3CX installed on aws you have vpc - Amazon virtual private cloud which isolates resources and networks.
Then you have another layer called AWS direct connect which links your local network to aws resources and these 2 are super related because they are the link to the fiber networks and gigabit links they have. This is like you have a mega firewall in location a, and all the other virtual aws servers in location b. You do not see this as an aws customer and you think they are the same little server or machine, but it is nothing like this. This is large scale networking implemented beautifully by amazon..

So you had to make changes to the vpc section. otherwise there is no chance ingress will work. Egress from machine will be ok because its "inside out" and inside is trusted as traffic originates from INSIDE AWS.. But you, your phone, are outside and therefore untrusted. So you need to tell the vpc on aws to allow stuff.
