I have an Asterisk server (11.25.1) which is running in VM. Initially I had configured only private static IP to this server and later I have configured public IP to this server. What I need is client behind NAT is also is able to access this server. So that only I have configured public IP. Everything seems to be good in local internet. But while using public internet like mobile data, audio is not hearing properly from public IP to local IP. But vice versa is working fine (local to public IP).
Local internet - Local internet :working fine
Local internet - Public internet :working fine
Public internet - Local internet :Noisy audio
Public internet - Public internet :Noisy audio
Port configurations (TCP & UDP) :
RTP -10000 to 20000
The above ports are opened in both public and private IP.
I have tried with all codecs. But I can’t able to trace out this issue. Please help to me fix this issue.
