In theory, yes.  But from what I've heard the longer you take to give out your call sign, the more likely it is that it will be stepped on, taken out by QSB, or both.  Speaking quickly but clearly seems to work best.  Once contact is made, the details on a the call sign can be verified and corrected while (most) everyone else backs off.  Then the pile-up can begin again.

My $.02,
