We have a problem with our VOIP phones receiving hundreds of Phantom phone calls in our NYC office. We know that this can be solved with a change in the settings on the router, but we are not sure what setting that is. Our VOIP people are not being very helpful.

May I know if you use a phone system at your office? Make and model? How many extensions do you have? Do you have access (credentials) to the Portal configuration?
