<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>This is more of mysql question then asterisk :D . Most voip providers
use 6 second rounding for costing . My asterisk server stores call cdr's
in mysql properly with billsec field containing number of billed seconds . I
want to know some function to round this to 6 seconds ( or any custom valud
like 30 seconds ) ..Suppose if billsec field is 3 seconds then it should round
to 6 seconds , if its 13 second then it should round up to 18 seconds ( for
6sec pulse counting ) . What would be mysql function to do this ? <br>
