I use VoxOx as a VoIP softphone. I seem to be able to receive calls on the softphone, but cannot dial out. The program seems to use random ports to dial out, so I cannot specify which ones are to be permitted through the firewall.
The program is set as a Trusted Application in the Application Rules.
I have also temporarily set the Global Rules to allow IP In/Out from the computer’s host name to any other address.
VoxOx works fine when I disable the firewall.
Does anyone have a suggestion on how to resolve this? I’ve hit my frustration limit!
When the ports for outgoing traffic are random I would suggest to allow all outgoing TCP and UDP traffic from this application. That may not give the amount of control you are seeking but the use of random ports for outgoing traffic seems to leave no other choice.
Yes, I have already done that. I have set the application to be trusted and set it to “allow all incoming and outgoing requests” and moved the rule to the top of the “application rules” list. Still no luck.
