Every 3 to 5 minutes I am receiving a call that is not being recorded on the ring central server. It is even a blocked number. It usually comes in as 8889207896. Earlier in the day I think it cam in as SIP vicious 101
I believe this may be what is called a SIP attach directly to my Polycom vvx 201.
Does anyone have a resolution for this type of problem. Ringcentral support had no solution and my ISP had no solution. Is there a way to block this fake call inside the polycom phone?
