I know that in the beginning of the NNN0xxx usage it was awkward,  
rather silly sounding especially on SSB, with the full phonetics.
Nowadays, on NAVMARCORMARS nets the 3 N's don't have to be  
phonetically spelled - you just say "En En En Zero" and only the 3  
last letters used phonetically. After the net is established and the  
check-ins are recognized, NCS announces that abbreviated call signs  
are authorized, and then only the 3 letter individual call signs are  
used - except the NCS call sign has to be used in full.
