Hi!
I'm having an issue with VoIP calls via TMG 2010 PPTP VPN. I have internal IP PBX and I want that I could register softphone to IP PBX through TMG VPN and make calls. At the moment softphone can register to IP PBX, I can make calls from internal phone to softphone though TMG VPN and from softphone to internal phones, but on internal phone I can't hear anything when I'm talking on softphone, but if i'm talking on internal phone I can hear on softphone. Where is the problem? Any ideas?
Rules looks like that:
1. Protocol RTP from ( VPN Clients ) --> to (IP PBX);
2. Protocol RTP from ( VPN Clients, IP PBX ) --> to (VPN Clients);
3. Protocol SIP from ( VPN Clients, IP PBX ) --> to (VPN Clients, IP PBX);
Regards
