Voip application via OpenVPN (Its Important) :(

  • Hello,

    I have a problem that I haven't found a solution for weeks.

    I set up an openvpn server with pfSense, set all voip settings of pfsense (except siproxd), voip server is in the remote location, there is an access via mpls voip phones are talking to voip server from mpls without nat.

    I gave PfSense an IP from the IP block of Voip phones to enable conversation with OpenVPN. Then I typed manual nat and said OpenVPN Ip block should turn into this ip while entering the server. (with the static port marked.)

    In the current situation, when I make a call after making a VPN, my voice is heard but the other party's voice is not coming to me.

    Could you help me please?
