    On the previous version of 3CX phone there were no issues with users vpn'ing in but with the new version the sdp connection info on the invite from the 3CX phone is the users local lan IP (192.168.1.50) even though the sip signalling IP (10.100.40.6) is correct. Obviously in this scenario audio doesn't work correctly.

    Hi pstulac. Did you ever find a solution to this? I was just trying to test something on a customer system remotely and ran into the same issue. RTP is being sent to one of my laptop's other IPs, one not available or the VPN, rather than to the VPN IP.

    Thanks,
    Matt

    Thanks Andreas. The next update will be fine. I completed my testing using a site to site VPN rather than the VPN client on my laptop.

    I know this post is very old but I think I ran into the same problem:

    3cx phone version 12.5.44178.0

    computer with one physical network interface and a virtual network interface created from openvpn.

    The connection work well but when I make a call in the SDP packet I found the wrong IP (the one of the physical interface) so I can make the call, the person on the other side can hear me (because my packet flow out into the vpn corrently) but I can't hear the person on the other side because the server try to send the incoming audio stream to the wrong IP.

    Anyone can suggest me a solution or a version that working?

    Thanks
