I have 2 VoIP providers setup in 3CX, Vonage and Broad Voice. Vonage is working great on out going and incoming calls. Broad Voice is working great on out going calls, but the incoming calls get dropped after 9 seconds. All ports are being forwarded by my router and all fire walls are turned off including windows. It gets dropped regardless of wether it is pickuped or it is going through the automated service. I have tried calling from different phones with the same result. Here is the server log. 10:39:56.796 StratInOut:nHangUp: Call from Ln:10001@Broad Voice to 101 has been terminated 10:39:48.406 CallLegImpl:nConnCfmd: ConnCfmd: 10001@L:1@C:17 10:39:48.312 CallLegImpl:nConnected: Connected: 10001@L:1@C:17 10:39:48.296 CallConf:nIncoming: Incoming call from Ln:10001@Broad Voice to sip:firstname.lastname@example.org Here are the configuration settings as suggested by others on the forum and Broad Voice.

So, far though I really like it. Any help would be great.
