<div>Dear All,</div>
<div> </div>
<div>I'm using PPTP VPN from home to office. After the VPN connection established, the SoftPhone can register to CCM server and begin to dial. But sometimes the VPN will be disconnected right after the call established. I have tried different broadband providers but the problem still occurs sometimes. I have tried to change the conference setting but didn't help and I can't figure out a fixed pattern for this problem. Does anybody have clue for this ? Thanks a lot for your help~
