Vonage plus a wireless router plus 58GHZ cordless phone system? - wireless phone system

I chose Vonage and buy a wireless router to the Internet simultaneously. I noticed static on the line, especially if the person is at the other end of the line (for example, unless I am). Applicants can not hear the other end of static, but I do. The system of cordless phone I bought to be "friendly wireless router, but I can not tell if the router or Vonage, the cause of the problem. I have all the instructions in the manual of your phone to resolve this problem, but without success . Everyone has the same problem and how to fix it?
