No idea what that one is caused by. Have you tried a different SIP provider?

[ruben23]

No i have not yet tried replacing my SIP provider..is it possible with the SIP provider or the bandwidth with our ISP? even single person is calling there is a disconnection on call & also....my bandwidth is also stable so far for 2Mbps downspeed & 256kbps on upspeed..I even tried using manual call there is also disconnection.....im confuse with this problem....& how to start isolate it..
