HI,   Issue: One way audio on VPN IP Phone.   Description: The VPN IP Phone is connected successfully on the internet as it was able to connect to the VPN. A call is successfully connected internally and externally.   However, the issue of one way audio is when a call is coming from an external number or calling an external number (e.g. mobile number). The receiver of the VPN IP Phone cannot hear anything but the other end receiver able to hear the voice coming from the VPN IP Phone.   Port Forwarding has been tried. DMZ has been tried. But, the issue is still the same.   The confusing part here is that, I have a colleague that is also with TPG NBN and now have the same modem that I have, is NOT encountering the issue.   Is it possible to verify or check from TPG side if any ports is getting blocked from my service address? or to check if there's any configuration that needs to be done from TPG's end to resolve this issue?   Additional notes: - This is not the normal phone at home. This is a VPN IP Phone. - Contacted the manufacturer of the modem (TP-Link) but didn't resolve the issue. - Contacted the internal network and cisco engineers in the office but still have the issue. They said that the modem is working (tested the VPN Phone as well) with Telstra and iiNet when they tested it. - TPG replaced my modem as well as part of the restart issue but still have the one way audio issue.   Thank you.   Regards, Louie ...
