[Freeswitch-users] Ghost Ringing from Verto Client when connection interrupted

Hello, I am using Freeswitch as WebRTC Gateway with mod_verto and mod_sofia. When some verto client suspend its laptop, the verto contact was keept on verto status (fs_cli -x 'verto status') . When verto client suspend its laptop, the connection is interrupted, the verto client didn't close the connection. When some SIP User make a call to that verto client, the call is ringing (It receives SIP Ringing). But the call never arrive to verto client. There is any way to avoid the SIP Ringing to SIP User, since this cause the feeling that it is ringing on verto client? Thanks in advance. Best Regards, Jose Lopes
