Not really, ph and matdyn give and read (by default) q-point in 
cartesian coordinates in units of 2pi/alat (alat is usually celldm(1)).

matdyn can read points in crystallographic coordinates with the switch 
q_in_cryst_coord=.true.

I think this is already the case, do you have any specific example where 
you think it is not?
