BUG in 3CX VoIP Phone 6.0.26523 i have problem, i have VPN (AVM VPN Driver) - this is as Net Service. This is not showed as interface, if i run ifconfig. If i call, on sip server showed my normal (not VPN) IP address, then SIP server hear me, but send me RTP to unroutable address... I try Phoner Lite and this normally works, SIP server show my VPN IP Address correctly (and not my LAN private address), then all works Okay. Then problem is in 3cx, not in VPN, i think. But Phoner Lite have poor audio quality for me :! Then i wish any hint for workarround (i try all possible combinations) or fix this issue... If need, i log traffic on my local machine. Thx. for any ideas.
