Sometimes I have a hard time getting my number to come across in an exchange. They'll copy everything right the first time but will bounce around between 2 and 6 are my most common. N2SAN or N6SAN..... I've tried communicating the number phonetically, but that rarely works. They'll just keep asking for my prefix. I do tend to talk fast, but am very conscious when this situation arrives and I slow it down. So my question is, how should I go about getting this to communicate correctly.
