How long would it take for my CNAM to be activated?
The changes to CNAM are not immediate. Allow a 72-hour update window; however, it may take weeks to get the National registry updated. Local carriers in the United States perform a “dip” to get a new list of CNAM matched to numbers. One customer may state that some customers see the correct name while another customer may not. RingCentral has no control over this. Many and smaller carriers do not "dip" very often as it costs them for each "dip."
