Extracting phone and fax for logged in user

I am trying to put the logged in user info in custom fields for a quote form rather than salesrep info...since default sales rep may not be the one issuing the quote.

I have been able to get the username and email address using getname() and getemail() but I do not see any commands for phone and fax.

Can anyone give me some suggestions.

var QInfo = nlapiGetContext();
var QContact = QInfo.getName();
var QEmail = QInfo.getEmail();
