Call Sign help

I’m trying to use the call sign, Reach-78 when flying an AMC C-17, but the ATC voice says Romeo-Echo-Alpha-Charlie-Hotel-Seven-Eight. How do I get the lady to just say the name? Thanks in advance.

Oh also, IPhone 5s

AFAIK it is not possible to form frases anymore to eliminate rude call signs. Otherwise you would have to have entered Reach but right know it gets automatically corrected to REACH

The reason it was introduced of you’d like to know, Philippe says “One can be visually (by the callsign) offended but not acoustically”.
