[otrs] tickets by phone

Hi All, I have an important question: I wanted to learn if there is someone who configured OTRS so that it works fine without providing an email address for a customer. Since it is possible that there are end users without email addresses (We are an old company :pp ), and agents can create tickets according to phone calls and close them by phone calls.. Thanks for your time, Best Regards, ibrahim __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
