192.168.1.xx are phone IP. On firewall i have created a policy where traffic from SBC IP to AWS public IP is allowed for any port and on AWS i have opened ports mentioned on documentation.
Can somebody explain why is this happening and what might be the solution?
SBC is installed on Hyper-V dedicated Windows 10 computer. No joined to domain or anything. No other functions in it.

So whenever you go looking for problems you will definitely find them. In this case I haven't seen you say the phones aren't working. Are they working?

 

[DritanB]

yes, we do have on and off working phones. Often we have to restart sbc even after uninstalling and installing it back on windows pc. Services often stop for no reason.
